Compatibility and related parts
Check that your motherboard is Micro ATX or Mini ITX, your graphics card is no longer than 280.0 mm, and any air cooler is no taller than 210.0 mm. For liquid cooling, AIO radiators go on the right side, and you can browse CPU coolers to find a matching size. The case takes a standard PS2 power supply, which is not included, so pick one from our power supplies. The PC builder checks compatibility for you, and we assemble and test the parts for free when you buy the case as part of a PC build.
