QUBE 540: Cooler Master’s Modular Mini Case

Cooler Master has unveiled the QUBE 540, a compact PC case designed for creators, gamers, and DIY enthusiasts seeking both flexibility and flair. The case supports multiple orientations—vertical or horizontal—allowing users to customize their setup to fit any workspace, from minimalist desks to studio shelves.

Compact Design, Infinite Possibilities

Keeping the clean geometric identity of the QUBE series, the QUBE 540 is crafted for modern living. Its 40.64-liter chassis comfortably fits high-end hardware while maintaining a small footprint, ideal for limited spaces like dorms or apartments. Available in two elegant finishes, Moonstone and Stardust Iron, this case blends seamlessly into both gaming rooms and creative studios. Users can adjust GPU clearance, airflow direction, and internal component layout—turning each build into a personal statement.

Modular Interior for Personalized Builds

True to its modular ethos, the QUBE 540’s interior allows every component to find its perfect place. It supports motherboards up to E-ATX (280 mm wide), flagship GPUs up to 415 mm, and 360 mm liquid-cooling systems. The case features repositionable I/O panels and movable handles that can be mounted on any side for convenience. Whether you prefer a vertical display or a flat desktop orientation, the QUBE 540 accommodates both effortlessly. Even first-time builders will appreciate the clear routing guides that make cable management a breeze.

Creativity Meets Open-Source Customization

Cooler Master is taking personalization a step further by offering open-source 3D printer files that let users print their own accessories—like headphone hooks or controller holders. The company has also teamed up with Prusa, a leader in 3D printing, to expand the library of printable parts and make creative customization more accessible to the community. The result: every QUBE 540 can become a one-of-a-kind creation that truly reflects the builder’s personality.

Ready for High-Performance Systems

Despite its small size, the QUBE 540 is engineered for serious power. It can host advanced cooling setups, large GPUs, and powerful CPUs while keeping noise and heat under control. With its modular airflow design and sturdy build, this case is ready for both professional workloads and immersive gaming marathons. As Wei Yang, General Manager of Cooler Master North America, puts it: “People want a case that adapts to their life, not the other way around.”

For those eager to start building, the QUBE 540 will soon be available through authorized retailers worldwide, with regional availability varying. For full details, visit Cooler Master.
