Cooler Master Launches QUBE 540 — A Compact PC Case Designed for Unlimited Creativity and Modern Living
Cooler Master, a global leader in PC components, peripherals, and tech lifestyle solutions, today announced the launch of the QUBE 540, a next-generation compact PC case engineered for flexibility, personalization, and performance. Designed for builders who demand both creativity and practicality, the QUBE 540 delivers unmatched adaptability in a sleek, geometric form that fits effortlessly into modern workspaces and living environments.
Compact Form, Infinite Possibilities
The QUBE 540 redefines what a compact PC case can be. With its innovative orientation flexibility, users can choose to build either a vertical or horizontal system, adapting their setup to suit their desk, shelf, or studio layout. This versatility allows the QUBE 540 to integrate seamlessly into any environment — whether it’s a minimalist home office, a creator’s workstation, or a student’s dorm room.
Inside, the QUBE 540 features a modular interior design that lets builders tailor the internal layout to their components, cooling preferences, and aesthetic goals. The case’s adaptable architecture makes it easy to optimize airflow paths, adjust GPU clearance, and position major components precisely where you want them. The result is a tidy, quiet, and performance-optimized system that reflects the individuality of each builder.
Despite its small footprint, the QUBE 540 retains the bold, geometric design language that defines the Cooler Master QUBE series — merging clean lines with functional innovation. It is available in two distinct finishes, Moonstone and Stardust Iron, giving users color options that blend naturally with both professional setups and personal spaces.
“People want a case that adapts to their life, not the other way around,” said Wei Yang, General Manager of Cooler Master North America. “With QUBE 540, users can choose a vertical or horizontal layout, move elements to optimize airflow and clearance, and personalize their builds with 3D-printable accessories. It’s a compact case that invites creativity without adding complexity.”
Compact Yet Powerful
While designed for space efficiency, the QUBE 540 makes no compromises when it comes to performance. The case supports motherboards ranging from Mini-ITX to E-ATX (up to 280 mm wide), providing builders with the freedom to select components that meet their performance needs.
Gamers and creators alike will appreciate its support for flagship graphics cards up to 415 mm in length and liquid-cooling radiators up to 360 mm. This ensures that even high-performance systems can run cool and quiet in a chassis that fits comfortably on or under a desk.
Cooler Master’s engineering team has also paid close attention to the build experience. Thoughtful cable routing channels, intuitive assembly guides, and ample tie-down points help even first-time builders achieve clean, professional results. Every detail — from screw placement to airflow optimization — has been refined to make the QUBE 540 both user-friendly and performance-ready.
Designed for the Maker Generation
One of the standout features of the QUBE 540 is its focus on customization and maker culture. In keeping with Cooler Master’s long-standing commitment to DIY creativity, the QUBE 540 supports 3D-printable accessories and community-driven design enhancements.
Users can download official and community-developed open-source 3D files to print accessories that enhance functionality or aesthetics — from custom panels to cable organizers, stands, and decorative trims. Cooler Master has also partnered with Prusa, a leading 3D printing company, to ensure easy access to high-quality printable designs for both beginners and experienced makers.
This open-source approach reflects Cooler Master’s vision of empowering the PC building community — giving every user the ability to make their system truly unique.
