Compatibility and related parts
Check that your graphics card is no longer than 410 mm and your air cooler is no taller than 165 mm; for liquid cooling, the top mount takes radiators up to 360 mm with a recommended maximum thickness of 55 mm. Pick an ATX unit from our power supplies that is ideally up to 170 mm long, and browse CPU coolers or extra case fans for the top slots. Our PC builder checks compatibility, and we assemble and test for free when the case is bought as part of a PC build.
