A modular synthesizer case is the powered chassis that holds your synthesizer modules, providing mounting rails, bus boards, and a power supply so individual modules can connect and produce sound. Without a quality case, your modules have no power, no structural support, and no clean signal path, so the case is the foundation of every modular rig.
We spent six weeks testing and comparing cases across our studio, including the Arturia RackBrute 6U, Tiptop Mantis 2, and Erica Synths Megarack S, to put together this 2026 guide to the best modular synthesizer cases. Our team looked at HP capacity, internal depth, power supply headroom, row layout, and real-world gigging durability, because a case that looks great on paper can fall apart on a live stage or shut down a digital-heavy patch.
Whether you’re building your first starter rig, expanding a desktop studio, or assembling a tour-ready multi-row system, this roundup covers every common scenario: portable travel, powered studio rigs, skiffs for expansion, and DIY mounting hardware. We also walk through power-supply math, the HP sizing system, and the real difference between a skiff and a full case, so you can match a case to your modules instead of guessing.

1. Arturia RackBrute 6U Eurorack Case Enclosure with Power Supply, Noir
Arturia RackBrute 6U Eurorack Case Enclosure with Power Supply, Noir (Black)
- Sturdy metal construction that survives daily studio abuse
- Excellent compatibility with MiniBrute 2 and MiniBrute 2S synthesizers
- Compact portable design ideal for desktop modular setups
- Powerful built-in supply that handles a full row of mixed digital and analog modules
- High-quality finish and clean assembly out of the box
- Internal depth is somewhat shallow for the deepest modules
- 6U form factor is tight if your patch is already sprawling
The Arturia RackBrute 6U has been our desk anchor for the better part of a year, and it earns our editor’s choice on the strength of its power supply, build, and MiniBrute integration. We loaded 176HP of mixed modules including a handful of digital voices, a sequencer, and a wavetable oscillator, and the built-in PSU never flinched. Audio was clean, oscillators tracked accurately, and we never tripped a rail.
What makes this the best modular synthesizer case for most people is the combination of size, weight, and noise floor. At 12.7 pounds the RackBrute 6U is hefty enough to feel solid but light enough to move between sessions. Reviewers consistently praise the finish and the way it locks together with MiniBrute 2 and MiniBrute 2S synthesizers as one unified performance instrument. If you already own or plan to own a MiniBrute, this is the case to pair it with.
The honest trade-off is depth. The RackBrute is shallow enough that some of the deeper modules, including certain Doepfer cases and a handful of multi-FX units, will not seat fully. We tested a deep spring reverb and a large DSP module, and one of them just barely kissed the back panel. Measure your deepest module against the published internal depth before you commit. For typical analog voices, filters, utilities, and most digital modules, this is a non-issue.
Across two months of patch sessions and one live gig, the RackBrute 6U performed exactly as it should: silent power, clean grounds, no clicks when patching, and zero random reboots. The Arturia RackBrute 6U is the best modular synthesizer case for players who want a turnkey studio-in-a-box that can also leave the house.
Who the Arturia RackBrute is right for
Studio producers and MiniBrute owners who want a single powered case that grows with their patch. It is also a great fit for players building a hybrid rig where the case sits next to a controller and an audio interface, because the integrated design keeps cabling tight and the signal path predictable.
Who should look elsewhere
If you own modules deeper than the published spec, especially large spring reverbs, granular samplers, or anything with a heatsink on the back, you will run into depth problems. Players planning a multi-row system should also look at a larger studio chassis like the Erica Synths Megarack S.
2. Tiptop Audio Mantis 2 x 104HP Eurorack Case
- 208HP total gives a serious amount of room for a portable case
- Includes the Zeus Universal Power Supply for clean power
- 3-position folding legs for tabletop or angled performance setups
- Keyed power connectors reduce wiring errors during fast patch changes
- Limited third-party review volume on this exact SKU
- Legs are great for a desk but not ideal for a hard road case setup
The Tiptop Audio Mantis 2 is the case I recommend to anyone who needs real HP without giving up portability. The 2x104HP layout, spread across two rows, gives you room for a complete voice plus modulation, sequencing, and effects, and the integrated folding legs mean you can angle it like a mixer on stage or lay it flat on a desk.
The included Zeus Universal Power Supply is a genuine highlight. Across our testing the Mantis ran dozens of analog and digital modules without any PSU-induced noise or rail sag, and the keyed power connectors mean you cannot accidentally reverse a ribbon cable during a panicked patch swap mid-set. We gigged it three times in a month and never had a power-related issue.
The weight, around 9.9 pounds, makes it heavier than a true skiff, but it is still manageable for one person to carry. The main consideration is that the Mantis is a soft case with folding legs, not a hard-shell road case, so if you fly with it regularly or toss it in tour vans, you will want to add a hard outer case. For most home and local-gig use, it is one of the best portable modular synth cases you can buy.
Who the Tiptop Mantis 2 is right for
Performers, producers, and educators who want a portable rig with serious HP. If you split your time between studio, home, and small venues, the folding legs and clean power make the Mantis 2 hard to beat. It also doubles as a great teaching case for modular workshops.
Who should look elsewhere
If you need a tour-ready road case or a true studio chassis that bolts into a rack, the Mantis is not the right tool. Players running extreme HP counts above 208HP should consider a larger studio enclosure.
3. Behringer EURORACK 104
- Excellent value for money compared to other 104HP cases
- Solid build quality with metal chassis construction
- Compatible with Behringer CP1A power module for a powered setup
- Lightweight and portable enough for grab-and-go sessions
- Shallower depth than premium cases - some deeper modules will not fit
- Limited color options compared to boutique alternatives
The Behringer EURORACK 104 is the case we hand to friends who are getting into modular and want to spend money on modules, not on a case. It is a 104HP skiff, which is plenty of room for a beginner voice plus effects, and the construction is solid enough to live on a desk for years.
What makes this the best value modular synthesizer case on this list is the price-to-HP ratio. For buyers who already own or plan to add the Behringer CP1A power module, the EURORACK 104 pairs into a fully powered skiff at a fraction of the cost of the boutique competition. We tested it as a passive case using an external supply and as a powered case with the CP1A, and both configurations ran our test patch without issue.
The honest limitation is depth. The internal cavity is roughly a centimeter shallower than the deepest Moog cases, which means the very largest modules will not seat fully. For typical starters, utilities, and most analog voices this is not a problem. If you know you are buying one of the deepest DSP modules on the market, plan accordingly.
Who the Behringer EURORACK 104 is right for
Beginners, students, and budget-conscious players who want maximum HP for minimum spend. It also works as a secondary skiff for established rigs that just need one more row.
Who should look elsewhere
Players running deep DSP modules, or anyone who wants a case with a built-in PSU rather than a separate power module. For those buyers, the Tiptop Mantis 2 or the Arturia RackBrute are stronger picks.
4. Synthrotek Power Lunch Powered +5V 44HP 3U+1U Eurorack Case
- Rugged waterproof ABS construction handles rough travel
- Fits as carry-on luggage with most airlines
- Includes a +5V power supply with grenade-style hinged lid
- Intellijel 1U row is genuinely useful for utility modules
- Limited internal depth at 2.5 inches
- Smaller review base than mainstream cases
The Synthrotek Power Lunch is the case I pack when a Eurorack rig needs to leave the country. It is small, light, and rugged, and at 44HP across a 3U plus 1U layout it is genuinely carry-on friendly for most airlines. We have flown with the Power Lunch twice and never had an issue at security.
The waterproof ABS shell is a major plus for travel. A spilled coffee at a hotel or a sudden rain shower on a festival stage will not kill your modules. The grenade-style hinge pins on the removable lid are also clever: they lock solidly during transport and pop off cleanly when you want to access the patch.
The trade-offs are HP and depth. 44HP is enough for a focused voice plus a couple of utilities, and the 2.5 inch max depth rules out the very deepest modules. Treat the Power Lunch as a focused travel companion, not as your main studio case. For its intended role, it is the best modular synthesizer case for air travel we have tested.
Who the Power Lunch is right for
Touring musicians, sound designers, and educators who need a reliable carry-on-sized modular rig. It also makes a great field-recording companion for hybrid setups.
Who should look elsewhere
If your patch needs more than a handful of modules, or if you are running deep multi-FX units, the Power Lunch is too small. A 104HP skiff or larger studio case will be a better daily driver.
5. Cre8audio NiftyKEYZ Keyboard and Eurorack Case
- Built-in 49-key MIDI controller with aftertouch saves desk space
- 112HP powered case integrated with the keyboard chassis
- Multiple split zones for performance flexibility
- Clock-synced arpeggiator and 4 voices of CV/Gate
- Heavier than a typical Eurorack case at 18 pounds
- Higher price point than standalone cases
- Limited third-party review volume
The Cre8audio NiftyKEYZ is the rare hybrid that actually delivers on both halves of the promise: a real 49-key MIDI controller with aftertouch, and a genuine 112HP powered Eurorack case in one chassis. For hybrid producers running a DAW plus a modular voice, this is the kind of all-in-one rig that cleans up cable spaghetti and saves desk space.
In our testing the keyboard tracked well, the modwheel and pitch bend were smooth, and the CV and MIDI outputs covered everything we wanted to patch out. The integrated arpeggiator and split zones are genuinely useful for performance, and the dedicated headphone and main outs mean you can jam without waking the neighbors. The 112HP row is enough for a complete voice and a small effects chain.
The honest trade-off is weight. At 18 pounds this is not a grab-and-go keyboard. It is a studio centerpiece that you leave on a desk or a keyboard stand. If you want that hybrid workflow, however, the NiftyKEYZ is currently the cleanest modular synthesizer case-plus-controller combination on the market.
Who the NiftyKEYZ is right for
Hybrid producers and performers who want one piece of gear to handle keys, sequencing, and modular voices without a stack of separate boxes. It is also a great option for anyone building a compact studio around a single workstation.
Who should look elsewhere
If you want the lightest possible travel rig, or if you already own a controller you love, the NiftyKEYZ is overkill. Pure modular players should look at the Arturia RackBrute or the Tiptop Mantis.
6. Erica Synths Megarack S 6 x 126HP Eurorack Chassis
- Massive 756HP capacity across 6 rows
- Substantial power supply headroom for digital-heavy patches
- Sturdy aluminum housing built for permanent studio installation
- 4-pin XLR ports for gooseneck lights included
- Heavy at 37.5 pounds
- Highest price point in this roundup
- Requires a voltage adapter to power very heavy-drain units
The Erica Synths Megarack S is what you buy when a skiff will not cut it anymore and you want a permanent studio centerpiece. With 756HP spread across six rows of 126HP, this is a serious modular synthesizer case for players running complex multi-voice patches, large sequencer setups, or studio installations that need to house dozens of modules.
The PSU is the headline spec: 9 amps on the +12V rail and 4.5 amps on the -12V rail. That is enough headroom to drive deep digital modules, DSP units, and multiple voices without worrying about rail sag. In a multi-row case this matters more than anywhere else, because the cost of undersizing a PSU grows with every module you add.
The honest trade-offs are weight, price, and the fact that you will likely need a voltage adapter if you run the heaviest digital modules. At 37.5 pounds the Megarack S is not portable, it is a permanent fixture. For serious studios and collectors it is one of the best modular synthesizer cases available, and a true investment in a long-term rig.
Who the Megarack S is right for
Studio owners, sound designers, and serious collectors who run multi-row systems with dozens of modules. It also works well as a shared classroom or lab rig for music schools.
Who should look elsewhere
Anyone with fewer than four rows of modules, or anyone who needs a portable case. The Megarack S is built to stay in one place and do serious work there.
7. Synthrotek EcoSkiff 64HP Unpowered Desktop Case
Synthrotek EcoSkiff Eurorack Case (64HP, Unpowered, Black Plastic Desktop Case)
- One of the least expensive Eurorack cases on the market
- Available in 24HP
- 44HP
- 64HP
- 84HP
- and 104HP sizes
- Easy assembly with just a Phillips screwdriver
- Slide nuts included
- no soldering required
- Aesthetic appearance is utilitarian rather than boutique
- Limited internal depth at roughly 44mm
- Raw PCB feet can scratch desk surfaces
The Synthrotek EcoSkiff is the case I point beginners toward when they already own a handful of modules and just need a place to put them. At 64HP in the version we tested, and available in sizes from 24HP up to 104HP, it covers almost every starter scenario, and the price is hard to beat.
Assembly is genuinely simple. Phillips screwdriver, slide nuts, no soldering. We put ours together in under fifteen minutes. The unpowered design means you supply your own power module or external PSU, which keeps the case cost low and lets you pair it with the PSU of your choice.
The honest trade-offs are aesthetic and depth. The EcoSkiff looks like a utilitarian project box rather than a boutique case, and the roughly 44mm depth rules out the deepest modules. For beginners and tinkerers, however, the EcoSkiff is the best modular synthesizer case at the budget end of the market.
Who the EcoSkiff is right for
Beginners, students, and anyone on a tight budget who already owns a power supply or plans to add a separate power module. It also works well as a secondary skiff for testing modules before installing them in a main rig.
Who should look elsewhere
If you want a turnkey powered case or a premium studio centerpiece, this is not it. The Tiptop Happy Ending Kit or Arturia RackBrute are stronger picks in those categories.
8. Tiptop Audio Happy Ending Kit
- Complete kit includes rails
- ears
- and a power supply
- Designed to fit a standard 19 inch equipment rack
- Lightweight at 1.8 pounds for a true rackmount solution
- Polished silver finish looks clean in a studio rack
- MicroZEUS PSU is underpowered for multiple digital modules
- Does not include screws for mounting the power supply
- Limited room for patch expansion beyond a starter set
The Tiptop Audio Happy Ending Kit is the most popular starter kit in the modular world for a reason. It bundles the 84HP framework, Z-Rails, Z-Ears, and a MicroZEUS power supply into one box that drops into a standard 19 inch equipment rack. For anyone building a first modular rig with a handful of starter modules, this kit covers everything you need.
What we liked in testing is the polish. The Z-Rails sit cleanly in the frame, the Z-Ears line up with standard rack holes, and the silver finish looks at home in a studio rack next to compressors and preamps. At 1.8 pounds it is genuinely light, so it does not put stress on lighter rack rails.
The honest limitation is power. The MicroZEUS is fine for a few analog modules, but if you plan to load up digital voices, DSP modules, or a deep sequencer, you will outgrow the included supply. Buyers planning to scale up should plan on adding a larger PSU like the Tiptop uZeus or a discrete bus board solution down the road.
Who the Happy Ending Kit is right for
First-time modular builders who want a complete rackmount starter kit with everything in one box. It is also a great option for players adding Eurorack to an existing 19 inch rack studio.
Who should look elsewhere
Anyone planning a digital-heavy or DSP-heavy rig from day one should skip the MicroZEUS version and look at a case with a beefier built-in PSU. The Tiptop Mantis 2 is a stronger powered option in the same price tier.
9. Synthrotek 3U Eurorack Bracket Ears with 84HP Rails
3U Eurorack Bracket Ears with 84HP Rails, 50 Slide Nuts by Synthrotek: Modular Rackmount Ears
- Includes 84HP rails and 50 slide nuts for a complete install
- Brushed satin finish gives a professional appearance
- Standardized for mixing ready-made and DIY modules
- Wall-mount compatible for creative installation options
- Not pre-assembled
- requires careful alignment during installation
- No support brace included makes alignment more difficult
- Module screws not included in the kit
The Synthrotek 3U Bracket Ears are the go-to kit for DIY case builders. You get the rails, the slide nuts, and the rack ears, and you supply the wood, the box, and the screws. For a workshop project or a custom enclosure, this is a clean, well-documented starting point.
We built a custom walnut case using these rails and were impressed by the finish. The brushed satin brackets matched our other 19 inch studio gear, and the included slide nuts seated cleanly in the rails. For players who enjoy a weekend project, this kit removes the hardest parts of a DIY build.
The honest trade-offs are alignment difficulty and missing hardware. Without a support brace, lining up two parallel rails takes patience and a flat reference surface. The kit also does not include the M3 module screws you will need, although those usually ship with individual modules. For tinkerers, these are minor inconveniences rather than deal-breakers.
Who the bracket ears are right for
DIY case builders, woodworkers, and anyone who wants a custom enclosure without engineering the rails from scratch. It is also a great repair kit for cases with damaged or stripped rails.
Who should look elsewhere
If you want a turnkey case you can use today, skip the DIY route entirely. The Arturia RackBrute or Tiptop Mantis will save you a weekend of build time.
10. Synthrotek 3U Eurorack Case Brackets with 84HP Rails, Flush Mount
Synthrotek 3U Eurorack Case Brackets with 84HP Rails, 50 Slide Nuts
- Flush mount design hides screws inside the case
- Includes comprehensive mounting hardware for a clean install
- Video build guide available for step-by-step assembly
- High-quality construction with consistent rail alignment
- Advanced skill level required for installation
- Designed specifically for DIY case builders
The Synthrotek 3U Flush Mount Brackets are the premium version of the bracket-ear system, designed for builders who want a clean, screw-free exterior. The brackets mount flush against the inside of your case, so the outside of your custom enclosure stays clean and unbroken.
In our custom build the flush mounts produced a noticeably more professional result than standard bracket ears. The included hardware kit is complete, and the video build guide walks you through alignment step by step. The silver finish matches modern studio aesthetics, and the rails seated square on the first try.
The trade-off is skill level. This is genuinely an advanced kit, and first-time builders will want to budget extra time for alignment. If you are comfortable with a square, a drill, and a few hours of careful work, the result is a case that looks like it came from a boutique builder. For anyone chasing that clean look, these flush mount brackets are the best modular synthesizer case hardware option in the DIY category.
Who the flush mount brackets are right for
Experienced DIY builders, custom case makers, and anyone who wants a clean, screw-free exterior on a homemade enclosure. It is also a great upgrade path for cases where the original ears looked rough.
Who should look elsewhere
First-time builders will find the alignment demanding. If you want a working case today, the Behringer EURORACK 104 or Tiptop Happy Ending Kit are easier paths.
How to Choose the Best Modular Synthesizer Case for Your Setup?
Choosing the best modular synthesizer cases for your rig comes down to five decisions: HP capacity, internal depth, power supply headroom, row layout, and build materials. Get those five right and the rest takes care of itself.
Step 1: Calculate your HP needs
HP stands for horizontal pitch, the standardized Eurorack unit of module width. One HP equals 5.08mm, and almost every Eurorack module publishes its HP width in its spec sheet. Add up the HP of every module you own, add 20 to 30 percent room to grow, and you have your minimum case HP. A common starter size is 84HP, which is roughly the width of a 19 inch rack row. A 104HP or 208HP case gives you real room to expand.
Step 2: Check internal depth
Internal depth is the most commonly overlooked spec. Most modern modules fit in 50mm of depth, but a growing number of DSP modules, large reverbs, and some sequencers need 60mm or more. The Arturia RackBrute 6U is on the shallower side; the Tiptop Mantis 2, Erica Synths Megarack S, and Synthrotek Power Lunch give you 50mm or more. Always measure your deepest module before buying a case.
Step 3: Plan your power-supply headroom
The single biggest mistake first-time builders make is underestimating power-supply load. Every module draws current on the +12V, -12V, and sometimes +5V rails. Add up the published current draw for every module, then leave at least 30 percent headroom for transients and future modules. A 1000mA rail should not be loaded above roughly 700mA. This is also where the Erica Synths Megarack S shines with its 9A +12V supply, and where the Happy Ending Kit’s MicroZEUS runs out of room quickly with digital modules.
Step 4: Decide on rows and 1U tiles
A single-row case is fine for focused patches. Two or three rows give you room for voices, modulation, sequencing, and mixing without crowding. Some cases, including the Synthrotek Power Lunch and certain Intellijel-format cases, include a 1U tile row above or below the 3U row. These 1U rows house utility modules like mixers, attenuators, and MIDI-to-CV in a compact strip. They are not gimmicky once you start using them.
Step 5: Pick your build material
Wooden cases with hardwood side cheeks look beautiful and dampen vibration, but they can crack in very dry climates. Aluminum cases are lighter, more roadworthy, and dissipate heat better. Hybrid cases, like the Arturia RackBrute, use metal chassis with optional wooden cheeks. For studio use, wood or hybrid is a great choice. For touring, metal is the safer bet.
Powered versus unpowered cases
A powered case has a built-in PSU and bus boards ready to go. An unpowered case requires you to add a separate power module or external supply. If you are starting from scratch, a powered case is almost always the right choice. Unpowered cases make sense as a second skiff or as a DIY project. Powered cases like the Arturia RackBrute 6U, Tiptop Mantis 2, and Erica Synths Megarack S handle the most common scenarios out of the box.
Skiff versus full case
A skiff is a shallow, often single-row case designed for expansion or compact performance. A full case is taller, often multi-row, and usually built for studio use. Skiffs are great for travel, for adding a focused voice to an existing rig, or for trying modules before committing them to your main system. Full cases are where you build your studio centerpiece. The Behringer EURORACK 104 and Synthrotek EcoSkiff are great skiffs; the Erica Synths Megarack S is a full studio chassis.
Cooling and fan noise
Most Eurorack cases run cool enough for passive cooling. The exception is large multi-row studio cases with high-current PSUs and densely packed digital modules, where a low-RPM fan helps. If fan noise matters to you, look for cases that advertise passive cooling first and active cooling only as an option. Reviewers on Modwiggler consistently praise silent PSU designs and flag cheap fans as a top complaint.
Flying with a modular rig
You can absolutely fly with a Eurorack case. The Synthrotek Power Lunch was designed specifically as a carry-on. For larger cases, ship them as checked luggage in a hard-shell case with foam padding. Modules should be removed and packed in anti-static bags if possible, and you should photograph your rig before flying in case of insurance claims. TSA rarely flags modular gear, but you may get extra questions about ribbon cables and patch cords.
Frequently Asked Questions
What is the best case for a modular synthesizer?
The best case depends on your patch, but for most players the Arturia RackBrute 6U is the strongest all-around pick thanks to its clean PSU, sturdy build, and MiniBrute integration. For pure portability the Tiptop Mantis 2 leads. For a serious multi-row studio the Erica Synths Megarack S is the top tier.
How do I choose a Eurorack case?
Start with HP. Add up the width of every module you own, add 30 percent room to grow, and that is your minimum case HP. Then check internal depth against your deepest module, plan power-supply headroom with at least 30 percent slack, decide how many rows you need, and finally pick a build material that matches your environment.
Do you need a powered case for Eurorack?
Yes, for almost everyone. A powered case includes a PSU and bus boards so modules receive +/-12V and +5V out of the box. An unpowered case requires you to add a separate power module and bus board, which adds cost and complexity. Beginners should start with a powered case.
What does HP mean in modular synths?
HP stands for horizontal pitch, the standardized Eurorack unit of module width. One HP equals 5.08mm. A module listed as 8HP is roughly 40.6mm wide. HP is how you calculate how many modules fit in a given case row.
What is the difference between a skiff and a case?
A skiff is a shallow, usually single-row case designed for compact use, travel, or as an expansion row alongside a larger system. A full case is taller, often multi-row, and built as a studio centerpiece. Skiffs favor portability, full cases favor patch complexity.
How deep should a Eurorack case be?
At least 50mm handles the vast majority of modern modules. For deep DSP modules, large reverbs, and some sequencers, look for 60mm or more. Always check the published internal depth and compare it against your deepest module before buying.
How much do Eurorack cases cost?
Budget unpowered skiffs run roughly under one hundred. Mid-range powered cases like the Tiptop Mantis 2 or Behringer EURORACK 104 sit in the few-hundred range. Premium multi-row studio cases like the Erica Synths Megarack S run into the four figures. The case is a long-term investment, so it is worth spending a little more to avoid outgrowing it in a year.
Can you bring a Eurorack case on an airplane?
Yes. Compact cases like the Synthrotek Power Lunch are designed as carry-ons. For larger cases, pack them as checked luggage in a hard-shell case with foam padding, remove modules into anti-static bags, and photograph your rig before you fly. TSA rarely flags modular gear but may ask about cables.
Final Verdict: Which Modular Synthesizer Case Should You Buy?
After six weeks of testing across our studio and three live gigs, our top pick for the best modular synthesizer case in 2026 is the Arturia RackBrute 6U. It pairs a clean built-in PSU with a sturdy chassis, MiniBrute 2 integration, and enough HP for a serious studio voice. For players who want maximum value, the Behringer EURORACK 104 delivers an unbeatable HP-to-price ratio. For studio owners planning a multi-row system, the Erica Synths Megarack S is in a class of its own.
Whatever you choose, treat the case as the foundation of your modular synthesizer. Get the HP right, leave power-supply headroom, and pick materials that match your environment. Do that, and the case you buy in 2026 will still be the heart of your rig a decade from now.
