Best Small Form Factor PC Cases: 6 Compact Mini-ITX Picks

If you want a gaming or home-theater PC that fits under a TV or on a shelf, the best small form factor PC cases are the place to start. Every case below takes only a Mini-ITX motherboard and still fits a full-size graphics card. This guide covers the best SFF cases for PC builders, from console-style towers to ultra-compact aluminium boxes. We have not hands-on tested these cases. The picks are based on manufacturer specifications and published reviewer feedback, and prices are approximate ranges that change often, so check the current listing before you buy.

What to Know Before Choosing a Small Form Factor Case

GPU length and thickness. Every case here lists a maximum GPU length between 322 and 356 mm. Compare it with your card, and check slot width as well, since some cases limit very thick cards.

CPU cooler height. Compact cases often cap cooler height at 48 to 70 mm in some layouts, which rules out many tower coolers. A 240 or 280 mm AIO is the usual alternative where supported.

Power supply. Several SFF cases use SFX or SFX-L power supplies. Confirm the PSU standard on the manufacturer page before ordering parts.

Size and portability. Volumes below range from about 10 to 18 litres. Only some cases are designed to be carried, so check for a handle if you plan to travel with the build.

Budget. The cases here sit at roughly 100 to 180 dollars, which is typical for the best small form factor cases for a PC build.

Small Form Factor PC Case FAQ

What is the best small form factor case for a gaming PC?

Based on published specs, the NR200P V2 offers the longest GPU clearance (356 mm) here, while the Meshroom D and Revolt 3 lean toward airflow and space. The best choice depends on your GPU and cooler.

Can small form factor cases use a full-size graphics card?

Many can. All six picks list GPU clearance of 322 mm or more, but you should check card length and slot width against the case limits.

Do SFF cases run hot?

Small volume leaves less margin, so cooler height limits and airflow matter. Mesh designs and AIO support, where listed, help. We have not measured temperatures ourselves.

Can I use a micro-ATX or ATX board in these cases?

No. Every case listed supports Mini-ITX only. If you need micro-ATX, look at a different class of case.
