About this product
The Cooler Master Qube 540 is a compact 40.6L ATX cabinet built for creators, gamers and DIY builders who want full-size capability without a full-size footprint. It keeps the clean geometric look of the Qube series while adding a fully modular interior, a repositionable I/O panel and movable handles, so the case adapts to your desk instead of the other way around. Despite the small frame it takes graphics cards up to 415 mm, 360 mm radiators on four sides and both ATX and SFX power supplies.
