Shrinking your PC down to a shoebox-sized tower sounds simple until you realize the case decides everything. The single most important number is graphics card clearance in millimeters, because your GPU is almost always the longest part you own. Every case below is built around Mini-ITX motherboards, so the real differences come down to GPU length, cooler height, power supply size, and how hot the inside gets once everything is stuffed in.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Measure your graphics card first, then your power supply, then decide how much internal breathing room you actually want. The right pick depends on your exact parts, which is why this breakdown of the best mini itx case options starts with fit.
Our Picks at a Glance
How To Choose a Mini ITX Case
Buying a Mini-ITX case is really a matching game. You are trying to fit four things into a box that is at least twenty times smaller than a full tower: your graphics card, your CPU cooler, your power supply, and your motherboard. Getting one wrong means a return and a rebuild. So start with the measurements, not the photos.
Graphics Card Length Is Your First Filter
Your graphics card is almost always the longest part in a Mini-ITX build, so its length in millimeters is the first number to check. A case rated for 360mm of clearance swallows a long triple-fan card, while one capped at 255mm means you are shopping for a compact card or a shorter model. Measure your card’s physical length, then leave yourself a few millimeters of wiggle room for the power cables that plug into the side.
Cooler Height Decides Your CPU Cooling
A low-profile air cooler needs as little as 60mm of clearance, while a full tower cooler can need 165mm or more. Bigger cases accept taller coolers, but smaller cases often force you into low-profile air cooling or a small liquid cooler (an all-in-one loop with a pump and radiator). The trade-off is simple: more cooler height usually means more noise headroom.
Power Supply Format Limits Your Options
SFX power supplies are physically smaller than standard ATX units, and many compact cases only accept SFX or SFX-L sizes. Some cases accept a full ATX supply, which is cheaper and easier to find, but it usually eats the space your graphics card wanted. Check the maximum power supply length in millimeters before you buy anything.

In‑Depth Reviews
1. Fractal Design Terra Jade – Wood Walnut Front Panel – Small Form Factor
Our pick — over 4.5★ from 700+ verified ratings; the strongest balance of quality and price.
The wood-front case that turns a tiny gaming rig into living-room furniture.
If you want a small PC that looks like it belongs on a shelf, this is the one. The Terra hides a 10.4-liter frame behind a front panel cut from FSC-certified solid walnut, and the anodized aluminum exterior includes an 8 mm-thick aluminum front. That 8mm slab is why it feels like a piece of furniture rather than a computer, and it swallows a graphics card up to 322 mm long. The JONSBO C6-ITX, by contrast, caps your GPU at 255 mm, so builders carrying a long triple-fan card have far more room to work with here.
The clever part is the stepless, slidable central wall. It gives you 30 mm of internal flexibility, letting you shift the balance between GPU space on one side and CPU cooler room on the other. Builders squeeze a ROG Strix B650E-I alongside a Thermalright AXP120-x67 with the spine at 2.5, leaving the fan just 4-5 mm from the side panel with no turbulence noise. You get two USB ports plus one USB Type-C 20Gbps on the front, an aluminum power button, and two internal bays.
The recurring gripe is assembly. This case is genuinely cramped to build in, cable management is difficult while you work, and the sandwich layout splits CPU and GPU cooling into separate airflow zones. That means the GPU can run cool while the CPU gets toasty under sustained load. What wins people over is the design, and the build quality genuinely feels premium. An occasional complaint notes an SFX-L power supply blocks the bottom fan, so keep that in mind if you plan a bigger PSU.
What Earns Its Keep
- Fits GPUs up to 322 mm inside a 10.4 L case
- Slidable central wall gives 30 mm of layout flexibility
- USB Type-C 20Gbps front port plus aluminum power button
- Solid walnut and 8 mm aluminum front panel
- Stays quiet from five feet away
Where It Pushes Back
- Tight, fiddly build with difficult cable management
- CPU can run warm since GPU and CPU use separate airflow
- SFX-L power supply blocks the bottom fan
- Premium price for the finishes
Made for: Builders who want a small tower that looks like decor and are happy to plan their parts carefully.
Think twice if: You want a fast, forgiving build or you run a hot high-wattage CPU with no patience for spine adjustments.
2. JONSBO C6-ITX Black Mini ITX Handled Mesh PC Case
A handled mesh box built for people who carry their tower between desks.
Most small cases assume your PC never moves. This one expects the opposite. An adjustable carry handle on top, held by Velcro fastener, makes it easy to pick up and go, and all four sides are mesh for serious heat-free ventilation. The number that makes it worth a look is CPU cooler support of up to 170 mm. That is a full tower air cooler in a Mini-ITX chassis, which almost no case this small allows. It also accepts ATX power supplies up to 140 mm instead of forcing an SFX unit on you.
The layout is genuinely thought through. The upper cover opens tool-free, the other three sides are topped from the inside, and the panel has a removable ventilation grille so fan installation is not a fight. You get a Type-C front port, one USB 3.0, and combined audio, plus four expansion slots. One build runs a deshrouded Dell 3090 with a Noctua NH-D15 G2 inside and still closes up, which speaks to how roomy the interior is for the footprint. It fits carry-on luggage check sizing too.
The honest catch is GPU length. Your card is capped at 255 mm, the shortest limit on this list, so a long triple-fan model simply will not go in. Airflow out of the top has been called sluggish under heavy load, and the workaround builders use is cracking the top cover during intensive tasks. Cable management is also tight, which is fair for a case this small. There is one internal 3.5-inch bay or one 2.5-inch SSD, so plan storage around that.
Why it stands out: A handled, mesh-everywhere chassis that fits a 170 mm tower cooler and an ATX power supply for a fraction of what premium small cases cost.
The trade-off: Your graphics card tops out at 255 mm, which rules out most long gaming cards, and top airflow needs a nudge during sustained load.
Reach for this if: You shuttle your PC between rooms or events and want big cooler support on a budget.
Look elsewhere if: Your graphics card measures longer than 255 mm.
3. SilverStone Technology Ultra Compact Mini-ITX Computer Case (SST-SG13B-USA)
Shoe-box dimensions that quietly swallow a standard graphics card and an ATX supply.
For a case that measures 11.5 liters, this thing accepts a lot. Standard-length expansion cards fit up to 10.5 inches, the motherboard tray takes Mini-DTX or Mini-ITX, and it handles a full ATX power supply instead of forcing an SFX unit. If you already own a standard power supply, that alone saves you a purchase. There is also room for a 120mm or 140mm single-fan all-in-one liquid cooler, and the front panel is mesh over a steel body.
Where it shines is temperature. A build pairing a B550M board, a 5060Ti, and a Corsair H60 AIO with three 80mm fans reports idle temps dropping from 63°C down to 38–42°C. Another build fits a Gigabyte B550I, a Ryzen 7 5800X, a 120mm AIO, and a 272mm RTX 4060 Eagle, running around 35°C at idle and under 60°C overclocked. For a home theater box tucked under a TV, that kind of headroom matters more than raw volume. It fits one 120mm front fan, and dust filtering is handled by a removable filter.
Two warnings. The front panel hides screws behind clips, and prying it off can snap those clips, so take it slow. Cable management is also genuinely difficult inside, and the top 2.5-inch mount can press against a GPU’s 8-pin connector. Space tightens up once everything is inside, and the case ships without fans, so budget for those separately. Builders also note the manual is online only.
Built For Tight Spaces
- 11.5 L footprint fits standard-length cards up to 10.5 inches
- Accepts an ATX power supply, not just SFX
- Room for a 120mm or 140mm single-fan liquid cooler
- Idle temps drop from 63°C to 38–42°C with a 120mm AIO and three 80mm fans
- Mesh front panel over a steel body with a removable dust filter
Plan Around These
- Front panel clips can snap if pried carelessly
- Cable management is nearly impossible once assembled
- Top 2.5-inch mount may press a GPU 8-pin connector
- No fans included and no printed manual
Best fit for: Home theater builds and travel rigs where a standard PSU and a compact GPU need to live in a very small box.
skip it if: You want an easy build with plenty of cable routing room.
4. KXRORS S300 Mini-ITX PC Gaming Case
Eight liters of aluminum and mesh that makes a first small build surprisingly painless.
Here is where sensible part matching pays off. The S300 holds Mini-ITX boards and graphics cards up to 305 mm, and it measures just 8.1 liters, so it is the tightest case on this list that still fits a long card. It uses three-sided mesh panels to keep hot and cold air moving, pure aluminum wire drawing on the exterior, and a small leather handle on top. You also get a USB 3.0 and a Type-C port up front, plus a bundled PCIe 3.0 16X riser cable.
Two fit numbers decide everything here. Your CPU cooler is capped at 60mm tall, which means low-profile air cooling, and your power supply must be SFX or SFX-L between 100 and 130mm. Builders squeeze an ASUS ROG Strix B760 mITX, an i7-13700, a Noctua 92mm low-profile cooler, a PNY 3070ti, and a 750W SFX supply inside, landing at 30-35°C idle and under 65°C on both CPU and GPU under load. This is the first ITX build for plenty of its owners, and most get there in under an hour.
There is one setup step you cannot skip. You must set the motherboard BIOS PCIe speed to GEN3 first, or the included 3.0 riser cable will not work and the computer will not boot. That trips people up. It also explains why some owners swap to a PCIe 4.0 riser instead. Thermal performance is the other variable: side mesh can be dense enough that hot chips run louder than expected, and the case has no real cable management, so wires hide wherever they land.
Small footprint, real card support: At 8.1 liters it is the tiniest case here that still swallows a 305 mm graphics card, and the bundled riser saves you a purchase.
Set it up right or not at all: You must switch the BIOS to PCIe GEN3 before installing the 3.0 riser, and the 60 mm cooler ceiling rules out tall air coolers.
Pick this one if: You are a first-time small-form-factor builder with a mid-length GPU and a slim CPU cooler.
Better to pass if: You plan to run a hot K-series chip or a tall tower cooler.
5. Silverstone Technology SUGO 16 Small Form Factor Case (SST-SG16B)
The all-steel case that sits on your desk without grabbing the spotlight.
Some builds want to be seen. This one wants to disappear into a corner of the desk without looking cheap. The SUGO 16 is 13 liters of perforated all-steel construction, with four of six sides ventilated for airflow and a top dust filter to catch the debris. It supports graphics cards up to 275 mm and takes Mini-DTX or Mini-ITX boards with a full ATX power supply. There is room for a 120mm all-in-one liquid cooler, and the back plate has a CPU cooler opening so you can swap coolers without pulling the whole board out.
For a case this plain, the cooling numbers are legitimately strong. A build with a 120mm AIO and a front fan in exhaust keeps a 7800X3D at 78°C maximum while the GPU stays under 65°C in games. Another owner runs a 65W Ryzen 3200G with no water cooling at all, landing at 33°C idle and under 60°C at full load. Builders consistently describe the panels as rigid and easy to pop off, which makes upgrades far less painful than they usually are on a small case. It fits two 2.5-inch drives.
Two things to know before you buy. First, the case ships without any fans included, so plan the airflow yourself. Second, cabling gets fiddly: one build took five times longer than a big case, with an SFX power supply zip-tied into its final position. The slide-out drive tray has also drawn criticism because right-angle SATA plugs cannot lie flat on it. Stick with SFX power, not ATX, and the build goes much more smoothly.
Quiet Strengths
- 275 mm graphics card support in a 13 L steel frame
- Four of six sides ventilated with a top dust filter
- Rear CPU cooler opening for easy cooler swaps
- Fits ATX power supplies and a 120mm AIO
- A 7800X3D peaks at 78°C while the GPU stays under 65°C in games
Before You Commit
- No case fans included
- SFX power supplies strongly preferred over ATX
- Assembly can take far longer than a standard build
- Slide-out drive tray awkward for right-angle SATA plugs
Suits you if: You want a finished-looking desktop box that cools well without water loops or flashy panels.
Not for you if: You expect bundled fans or a plug-and-play experience.
6. Fractal Design Node 304 Mini ITX Cube Case
Six hard drives in a mini cube built for quieter home-server duty.
If your priority is hoarding data instead of chasing the smallest footprint, this cube earns its spot. The modular mounting system accommodates up to six 3.5-inch HDDs or 2.5-inch SSDs, it takes ATX power supplies, and it accepts tower CPU coolers up to 165mm tall plus single-fan water cooling. Three Silent Series R2 hydraulic bearing fans come included with a fan controller, so you are not buying cooling separately. That is a far cry from the single internal bay on the JONSBO C6-ITX, which trades capacity for portability.
Graphics cards fit up to 12 inches long once two HDD brackets come out, which means starting with storage and scaling back later is entirely doable. Filtered air intakes keep dust out of the internals, and you get a front USB 3.0 port. Builders regularly choose this for unRAID media servers and home theater boxes at the bottom of a cabinet, noting the fans run very quiet on low and medium settings. The minimalist exterior with its fingerprint-resistant front makes it fit right in under a TV.
The main limit is that not everything fits at once. A full-length card, a full-size cooler, and all six drives will not coexist, so you pick your priorities. Cable space gets tight once a GPU is added, and the case caps power supplies at 160mm. The inclusion of only four SATA ports on many Mini-ITX boards also means you cannot populate all six bays without an extra card. Some builds also note the brightness of the activity LEDs.
The case for it: Six drive bays, three included quiet fans, and 165 mm of cooler clearance make this the storage-first pick for NAS and server builds.
The reality check: You cannot run six drives, a full-length GPU, and a tower cooler all at once, and the 160 mm power supply limit is tight.
Built for: Media servers and NAS boxes that need lots of storage bays and quiet operation over tiny dimensions.
Wrong pick if: You want the smallest possible footprint or your heart is set on a full-length GPU with all bays filled.
7. SSUPD Meshroom D Mini-ITX Small Form Factor Case
Full mesh on every side, with room for two radiators and a three-and-a-half slot card.
For a case this small, the fit list is unusually long. The Meshroom D measures 14.93 liters and is built exclusively for Mini-ITX boards, but it supports 3.5-slot graphics cards, dual radiator custom loop configurations, and any of SFX, SFX-L, or ATX power supplies. Inside, it fits up to three 140mm cooling fans plus multiple radiators. The mesh panels use an extremely fine 1.5mm aperture across all sides, which is why air moves so freely through it. Tool-free power supply mounting means fewer screws during the build.
Three 120mm fans plus an 80mm fan fit in one setup, and builders report excellent air-cooled temperatures and superb flexibility for hardware mounting. The feet are invertible with extra holes for the power socket and button, which lets you reposition the case for a cleaner desk layout. Owners strongly recommend flipping the standard orientation because it reportedly drops temperatures noticeably. A used unit arriving looking brand new is a common-enough story that build quality and finish hold up well over time.
The trade-offs are real though. The mesh panels are light and warp-prone, and the clips that hold them can be hard to relocate once moved. Fitting a 160mm ATX power supply takes trial and error, though SFX opens up more configuration options. GPU power cable clearance is tight, the rear piping holes lack grommets, and the bottom mesh is flimsier than the sides. None of it stops air-cooled builds from running cool, but it means you should factor in a bit of finesse.
Where It Delivers
- Fits 3.5-slot GPUs and dual radiator loops in 14.93 L
- Supports SFX, SFX-L, or ATX power supplies
- Fine 1.5mm mesh on all sides for strong airflow
- Fits up to three 140mm fans inside
- Invertible feet with alternate socket and button holes
What Takes Patience
- Thin panels can warp and clips are hard to move once set
- 160mm ATX power supply requires trial and error
- GPU power cable clearance is tight
- Rear piping holes lack grommets and bottom mesh feels flimsy
Ideal for: Custom loop builders and airflow-focused builders who want maximum hardware in a compact mesh shell.
Not right for: Anyone who wants rigid panels and clip-free side covers.
8. Thermaltake TR100 SFF Chassis (Matcha Green)
A dual-chamber 18.9-liter box built to take a 360mm card on the road.
The TR100 solves a specific problem: you want genuinely big graphics card support but still call it small. It runs 18.9 liters in a dual-chamber design, fits Mini-ITX boards, and clears up to 360mm of GPU length with an included PCIe 4.0 riser cable. A removable PCIe bracket makes sliding a card in straightforward, and an integrated GPU brace keeps it secure once it is mounted. Power comes from SFX or SFX-L units, and there is 68mm of CPU cooler clearance. Storage supports 2.5-inch and 3.5-inch drives.
The build experience wins people over fast. Cable routing is easy to tuck away, magnetic panels lift off without a fuss, and the overall assembly is described as very easy to build in. A finished build pairing an AIO cooler and an RTX 4070 fits without clearance problems. The removable GPU slot and power supply tray make working inside simpler than most small cases allow, and the thick metal panels and thumb screws give it a sturdier feel than the price suggests. Owners say it looks even better in person than in photos.
There is one cramp worth flagging. The internal power extension cable sits in the way of a 280mm radiator fitted with thick 30mm fans, and one owner had to bend and shave the cable to make it work. If you are planning that exact combination, plan around it. Some buyers also report radiator compatibility mismatches more broadly, so check your specific cooler before you commit. Otherwise the interior feels roomier than expected for 18.9 liters.
Portability meets capacity: 360 mm of GPU clearance, an included PCIe 4.0 riser, and a removable PCIe bracket in a chassis small enough to travel.
Watch that one cable: The internal power extension cable blocks a 280mm radiator with thick 30mm fans, and some report radiator fit issues.
Choose it for: A travel-friendly build with a long graphics card and easy cable management.
Reconsider if: A 280mm AIO with thick fans is the plan.
9. Cooler Master NR200P V3 Mini-ITX PC Case
Vertical graphics mounting for flagship cards inside an 18.6-liter frame.
This is the case for anyone refusing to compromise on the GPU. The NR200P V3 runs 18.6 liters in a Mini-ITX-only chassis and supports vertically mounted graphics cards up to 361.5 mm, including RTX 5090 and RX 9070 XT class models, with a bundled PCIe 5.0 riser cable. It also accepts top-mounted 240mm or 280mm radiators and uses tool-free aluminum and mesh side panels for quick access. A vented mesh side panel can be removed to show off the vertically mounted card. Note it takes only SFX power supplies up to 130mm long.
The ventilation is the standout. One build with a Gigabyte RTX 5070 Ti and an AMD 9950X3D paired with an NZXT Z63 cooler fits with a tight but good fit. Another reports 48°C on the GPU and 60-65°C on the CPU while gaming. Some owners say no extra fans are needed at all because the GPU fans rarely spin up outside of intensive games, which is genuinely unusual for a case this small. That airflow design means quiet operation for most everyday use.
Fit is the thing to double-check. The GPU slot dimension is the catch: a 3.5-slot card can fit lengthwise but end up too thick slot-wise, causing a few millimeters of sag. One builder swapped the included riser for a thinner-profile PCIe riser and raised the GPU on spacers to get 120mm intake fans underneath. The vertical layout also blocks RGB lighting from view, and floor space runs out fast for extra fans or wires. But the temperatures and looks hold up once you get the parts right.
Big-card capability: 361.5 mm of vertical GPU room and a PCIe 5.0 riser make this the pick for flagship graphics hardware in a small footprint.
Fit matters more than volume: Chunkier cards can sag a few millimeters, and a thinner riser may be needed to fit intake fans underneath.
Made for: Builders mounting a long, thick flagship card vertically and cooling a beefy CPU with a top-mounted radiator.
Skip if: You need room for lights and extra fans, or a full-size ATX power supply.
Understanding the Specs
Graphics Card Clearance
This is the maximum length of graphics card that physically fits inside, measured in millimeters or inches. Your card’s length includes the PCIe bracket at the back plate, so measure the whole unit, not just the shroud. Graphics card support of 361.5mm fits a triple-fan flagship card, while a cap of 255mm limits you to mid-length models. Always leave a few extra millimeters for the power connector on the card’s edge, which often gets in the way.
Power Supply Format
SFX power supplies are physically smaller than ATX units and take up less internal space, which leaves more room for your graphics card and cooling. Some cases accept SFX-L, which is a slightly longer SFX variant, and some accept full ATX. Cases often specify a maximum length in millimeters, and going over that limit either removes your GPU space or stops the build from working. If you already own an ATX supply, check the case’s supported format before you commit.

Final Thoughts: The Verdict
For most builders, the best mini itx case winner is the Fractal Design Terra Jade because it fits a 322mm graphics card inside 10.4 liters while wearing a solid walnut front and slidable central wall. If you want a handled, mesh box with big cooler support at a budget-friendly tier, grab the JONSBO C6-ITX. And for a home theater or travel build that needs a standard ATX power supply and compact size, the SilverStone SG13B is the one to reach for. If pure cooling capacity is the goal, the Cooler Master NR200P V3 withits 361.5mm vertical GPU support and PCIe 5.0 riser is the pick to beat. Whatever you choose, measure your graphics card and power supply first — those two numbers decide which cases here will actually fit your build.
