Pros
- 26.3 liter footprint still clears GPUs up to 415mm, so full-size cards fit a compact build
- Steel mesh side and top panels open up airflow for high-TDP cards and radiator setups
- Supports a 360mm radiator plus up to ten 120mm fans across the chassis
- Front and side PSU mounting works with ATX, SFX, SFX-L and LIAN LI EDGE supplies
- Walnut wood front panel adds a distinct finish next to the usual all-metal or glass fronts
Cons
- No fans ship in the box, so cooling has to be bought and added separately
- 4 expansion slots cap it to mATX/ITX boards, full ATX motherboards will not fit
- Wood front panel needs the same care as furniture finishes, unlike a wipe-down metal or glass panel
At 17.4 x 7.63 x 12 inches, the A3-mATX packs a 26.3 liter volume that still clears graphics cards up to 415mm long. Steel mesh panels on the side and top are designed specifically to move air through high-TDP GPUs and radiator setups rather than trap heat inside a closed shell.
- 26.3 liter internal volume in a compact mATX/ITX footprint
- GPU clearance up to 415mm, enough for most full-size graphics cards
- Mesh side and top panels prioritize airflow over a fully enclosed look
The compact size makes it a strong fit for small-form-factor builds that still need room for high-end hardware, rather than a true mini-ITX-only chassis.
The chassis accepts mATX and ITX motherboards across 4 expansion slots, and supports front or side PSU mounting compatible with ATX, SFX, SFX-L and LIAN LI's own EDGE power supplies. This flexibility lets builders orient the power supply to whichever side offers better cable routing for their layout.
- mATX and ITX motherboard support across 4 expansion slots
- Front or side PSU installation compatible with ATX, SFX, SFX-L and EDGE units
- Modular internal layout supports repositioning parts as the build evolves
Full ATX motherboards are not supported given the 4-slot limit, so builders should confirm their board size before purchase.
The case supports a 360mm radiator alongside up to 10 individual 120mm fans, giving serious headroom for liquid cooling in a small chassis. No fans are included, so cooling has to be assembled separately to match the intended thermal load.
- 360mm radiator support for all-in-one liquid coolers
- Up to 10 x 120mm fan mounting points across the chassis
- No fans included, plan to add case fans or an AIO separately
The walnut wood front panel and modular structure are built for builders who plan to revisit the internal layout over time, rather than a fixed one-time build, making later upgrades more straightforward than in a rigid steel-only case.

Pros
- 11.5-liter internal volume fits Mini-ITX and Mini-DTX boards alongside a full-size ATX power supply
- Clears CPU air coolers up to 61mm with the stock ATX PSU mount, or 82mm with the separate SFX adapter
- Front panel accepts a single 120mm or 140mm fan, or a matching all-in-one liquid cooler
- Holds one 3.5" and one 2.5" drive together, or three 2.5" drives on their own
- Front bay accepts expansion cards up to 10.5 inches long
Cons
- 61mm CPU cooler clearance with the stock ATX PSU mount is tight for larger tower air coolers
- A 140mm-class fan or cooler cuts front GPU clearance down to roughly 9.5 inches
- SFX power supply compatibility needs the separately sold PP08B adapter, not included in the box
The SG13B keeps a full-size build inside an 11.5-liter shell measuring 8.74 inches deep, 11.22 inches wide, and 7.13 inches tall. It is built around a Mini-ITX or Mini-DTX motherboard paired with a standard ATX power supply, so builders are not locked into small-form-factor-only components for the PSU.
- 11.5-liter internal volume in an 8.74"D x 11.22"W x 7.13"H steel body
- Front panel accepts expansion cards up to 10.5 inches long
- Storage holds one 3.5-inch and one 2.5-inch drive together, or three 2.5-inch drives alone
The steel chassis with a mesh or solid front panel option keeps the footprint small enough for a desk or shelf while still fitting drives and cards sized for a full desktop build rather than a laptop-class mini PC.
Cooling in the SG13B is configurable rather than fixed. Builders can run the case with no active front cooling, add a single 120mm or 140mm fan to the front panel, or mount a 120mm/140mm single-fan all-in-one liquid cooler in the same location.
- Supports one 120mm or 140mm fan, or a matching single-fan AIO cooler, in the front panel
- Standard ATX PSU mount clears CPU air coolers up to 61mm tall
- A 140mm-class fan takes about 1 inch of the 10.5-inch card space, leaving roughly 9.5 inches for a graphics card
Because the front bay does double duty for fans, coolers, and card clearance, the choice of cooling method directly affects how long a graphics card can be before it interferes with airflow components.
The case ships set up for a standard ATX power supply and can fit units up to 150mm long, which is the configuration that limits CPU cooler height to 61mm. Builders who want more clearance can switch to an SFX power supply using the separately available SilverStone PP08B ATX-to-SFX adapter.
- Stock ATX PSU mount fits power supplies up to 150mm long
- Switching to SFX with the PP08B adapter frees up an additional 21mm of internal space
- That extra space raises CPU air cooler clearance from 61mm to 82mm
This means the practical cooler height in the SG13B depends on which power supply format is installed, so builders planning a taller air cooler should plan for the SFX adapter rather than assuming the stock ATX clearance will fit.
Pros
- Supports GPUs up to 255mm and CPU coolers up to 75mm tall, covering most mid-range builds
- Mesh panels on all sides plus 3 fan positions (front, top, bottom) support active airflow
- Tool-free upper cover and side panel speed up cable routing and component swaps
- Front I/O includes a 20-pin USB Type-C port alongside USB 3.0 and a combo audio/mic jack
- Compact 202mm x 266mm x 295.2mm footprint fits ITX and M-ATX boards in tight desk spaces
Cons
- 75mm cooler clearance rules out tower air coolers, so a low-profile or AIO cooler is needed
- Drive bay space is limited to one 3.5" HDD or two 2.5" SSDs, tight for anyone stacking multiple storage drives
- ATX power supply length is capped at 185mm, which excludes some longer fully modular PSUs
Overall case size is 202mm (W) x 266mm (D) x 295.2mm (H) including the footpad, built around an alloy steel frame with mesh panels on the front, top, and sides for airflow. Fan mounting supports a 120mm or 140mm fan on top, a 120mm or 140mm fan on the bottom, and a 120mm fan up front, or an HDD bay in that same front position.
Drive support covers one 3.5" HDD or two 2.5" SSDs. Front-panel connectivity includes a 20-pin USB Type-C port, one USB 3.0 port, and a combined audio/mic jack, giving modern front-panel connectivity without needing a separate adapter cable for USB-C headsets or drives.
Motherboard support is limited to ITX and M-ATX boards only — full ATX motherboards will not fit this chassis. Power supply length is capped at 185mm, which fits most standard ATX PSUs but excludes some longer, fully modular units common in high-wattage builds.
CPU cooler clearance tops out at 75mm, ruling out tall tower air coolers in favor of low-profile air coolers or an all-in-one liquid cooler. Graphics card clearance runs from 200mm to 255mm, which covers most mid-range cards but should be checked against longer flagship GPUs before buying.
The upper cover and side panel are tool-free, so accessing the interior for cable routing or a component swap does not require a screwdriver for those panels. This makes incremental upgrades, such as adding a second SSD or swapping the GPU, faster than in cases requiring full panel removal with screws.
Because the case is built specifically around ITX/M-ATX boards, the realistic upgrade path is limited to components that fit the 75mm cooler height, 255mm GPU length, and 185mm PSU length ceilings — this is a case for compact builds rather than one meant to grow into a full ATX tower later.
What to Check Before You Buy a Mini ITX Case
Small form factor cases look similar in photos, but the internal layout varies a lot between brands. Before you compare spec sheets, get clear on four things: how big your graphics card is, how much airflow you actually need, what power supply format the case takes, and whether your cooler will physically fit. Getting any one of these wrong usually means a return shipment.
GPU Length and Clearance
Most modern flagship graphics cards run 320mm or longer, and some triple-fan models exceed 340mm. Check the case’s maximum GPU length with the front panel or dust filter installed, not the number printed on the box alone, since real-world clearance is often a few millimeters tighter. If you’re running a card like an RTX 4080 or 4090, look for a case rated for 330mm-plus support with room for radiator hoses.
Airflow vs. Silence
Mesh-front cases move more air and run cooler, but they let in more noise from your fans and drives. Solid-panel or wood-front designs look cleaner on a desk and dampen sound, though they usually run a few degrees warmer under load. Decide which trade-off matters more for where the PC will actually sit — under a desk, on top of it, or in a media cabinet.
PSU Format: SFX vs Full-Size ATX
Most true mini ITX cases require an SFX or SFX-L power supply, which is physically shorter than a standard ATX unit. A few larger micro-ATX-adjacent cases fit full ATX PSUs, giving you more wattage options at a lower cost per watt. If you already own an ATX power supply, confirm compatibility before you buy a case built strictly around SFX.
Motherboard and Cooler Compatibility
Double-check whether the case is built for pure mini-ITX boards or also accepts micro-ATX, since a few “mini” cases actually support both. CPU cooler height matters too — air coolers over 160mm won’t close in a lot of small cases, so either check the spec or plan on an AIO liquid cooler instead.
Best Mini ITX PC Cases for Different Builds
Once you know your GPU length and PSU format, matching a case to your use case is straightforward. Here are the picks worth considering, organized by what you’re actually trying to do with the build.
Best Overall: Balanced Airflow and Build Quality
The NZXT H2 Flow earns the top spot for a reason: it packs two included 120mm top fans, a PCIe 5.0 riser, and genuinely usable cable management into a 20.7-liter shell. It’s rated at 4.8 out of 5 stars from buyers, which is unusually high for a small form factor case. If you want strong airflow without hunting for extra fans or a riser cable separately, this is the one to check the current price on for your build.
Best for High-End GPUs and All-in-One Builds
The Cooler Master NR200P MAX V2 is a different animal — it’s sold as a bundle with a 280mm AIO cooler and an 850W SFX Gold power supply already installed. That means less shopping and less risk of a compatibility mismatch, at a higher price point. It supports graphics cards up to 357.6mm, so it’s worth a look if you’re building around a full-length flagship GPU and want the vertical mount option.
Best Budget Pick
The SilverStone SG13 keeps things simple: a compact mesh-front shell with no frills, priced well under $100. It won’t fit the longest graphics cards on the market, but for a compact office or streaming-box build with a mid-range GPU, it does the job without cutting corners on airflow. It’s a reasonable starting point if this is your first small form factor build.
Best for a Furniture-Grade Look
If the PC is going to sit somewhere visible — a living room shelf, a desk in a shared space — the Fractal Design Terra Jade is worth the extra cost. Its walnut front panel and anodized aluminum construction look more like an audio component than a gaming PC, and it still includes a PCIe 4.0 riser and USB-C front port. The trade-off is airflow: solid panels breathe less than mesh, so pair it with efficient components if you’re pushing a hot GPU.
Best Ultra-Compact Build
The HYTE Revolt 3 is built for people who want the smallest possible footprint without switching to a mini PC. Its all-metal shell keeps the design minimal, and buyers consistently mention how solid the panels feel compared to cheaper alternatives. If portability matters — LAN parties, moving between rooms — the JONSBO C6-ITX is also worth comparing, since it adds a carrying handle and tool-free panels for quick access.
Common Mistakes to Avoid When Buying a Small Form Factor Case
Small form factor shopping has a few traps that don’t show up with full-tower cases. Here’s what trips people up most often:
- Ignoring radiator clearance. A case might list “supports 280mm AIO” but only with specific fan thickness — thicker radiators or push-pull fan setups can hit the GPU or motherboard.
- Buying an ATX PSU for an SFX-only case. Always confirm PSU format before checkout; this is the single most common return reason for small cases.
- Underestimating cable management time. Tight cases take longer to build in than a full tower — budget extra time your first time around.
- Skipping dust filter maintenance. Mesh cases pull in more dust with their higher airflow, so plan on cleaning filters more often than you would with a bigger case.
- Assuming “mini” always means the smallest option. Some cases marketed for mini ITX boards are actually closer in volume to compact PC cases built for micro-ATX boards — check the listed liters, not just the name.
Mini ITX vs Micro-ATX: Which Small Form Factor Actually Fits You
Mini ITX cases are the smallest mainstream option, typically under 25 liters, and they force you to buy a mini-ITX motherboard with a single expansion slot. That’s fine for a GPU-focused gaming or streaming build, but it limits future upgrades like extra M.2 drives or add-in cards. If you want a bit more room to grow, browsing our guide to the best microatx pc cases is worth doing before you commit, since micro-ATX boards offer more expansion slots for a modest size increase.
On the other end, if raw size isn’t a constraint and you mainly care about airflow and GPU support, our roundup of the best ATX PC cases covers larger builds with more cooling headroom. And if you’re specifically chasing a build for competitive play rather than just a small desk footprint, our best PC cases for gaming guide compares options built around sustained thermal performance.
Frequently Asked Questions
Can a mini ITX case fit a full-size graphics card?
Yes, but you need to check the listed maximum GPU length with the front panel installed. Cases like the Cooler Master NR200P MAX V2 support cards up to 357.6mm, which covers nearly every flagship GPU on the market today.
Do mini ITX cases run hotter than full towers?
They can, simply because there’s less internal volume for air to circulate. Mesh-front designs with dedicated intake fans close most of that gap, while solid or wood-panel cases tend to run several degrees warmer under sustained load.
What power supply do I need for a mini ITX build?
Most mini ITX cases require an SFX or SFX-L power supply rather than a standard ATX unit, since the shorter length is what allows the smaller case footprint. Always confirm the exact PSU format listed for your chosen case before ordering one separately.
Is it harder to build in a small form factor case?
Cable routing and component installation generally take longer in tight cases simply because there’s less room to work. Tool-free panels and removable side panels, both common in newer designs, make the process noticeably easier than older compact cases.
How many fans should a mini ITX case have?
Two to three fans is typical for good airflow in a compact case — usually one or two intake fans plus an exhaust, or a top-mounted pair like the NZXT H2 Flow includes out of the box. Adding more than that rarely helps much once the case itself is airflow-optimized.
Picking a small form factor case really comes down to matching the internal layout to your GPU and PSU rather than chasing the smallest liter count you can find. Start with the clearance numbers for your specific graphics card, decide how much you value airflow over a quiet desk footprint, and the rest of the shortlist above should narrow itself down quickly.
