Game in a New Light. Vivid Performance. The Cooler Master MasterBox 540 is a mid-tower chassis designed for enthusiasts who want a visually stunning build without sacrificing high-end component compatibility. Its centerpiece is a striking, automotive-inspired “Ether” front panel that features customizable ARGB strips radiating behind a transparent façade. Beyond its iridescent aesthetics, the MasterBox 540 features a user-friendly design with a completely removable top panel and a tool-free tempered glass side, making it a dream for both first-time builders and seasoned pros.
ARGB Ether Front Panel: Inspired by automotive lighting design, the front panel houses ARGB strips paired with a front diffuser. This unique element is powered by a pogo-pin connector and fused to the DarkMirror finish, providing a sophisticated twist on conventional case lighting.
Standardized ARGB Controller Included: Control the vivid front panel via your motherboard software or the included ARGB controller. The controller comes pre-loaded with unique lighting presets and is pre-routed to the front panel Reset/ARGB button for instant customization.
Removable Top Panel: The entire top panel can be removed, offering unobstructed access to internal components. This “zero-compromise” body design makes it significantly easier to install large radiators, route cables, and mount fans.
Rich Connectivity: The I/O panel is equipped for modern hardware, featuring a USB 3.2 Gen 2 Type-C port, two USB 3.2 Gen 1 Type-A ports, and a combined 3.5mm audio jack for high-speed data transfer and easy peripheral connection.
Screwless & Tool-Free TG Side Panel: The tempered glass side panel is secured with pins for easy removal, facilitating quick access to the internals. An optional screw can be installed for added security during transport.
Breathable Power Supply Shroud: The PSU cover is ventilated on top, allowing you to install actively cooled units with the fan facing either up or down. It also provides the necessary airflow for passively cooled power supplies.
Extensive Clearance for Upgrades: Designed to stay ahead of the game, the 540 supports flagship hardware, including graphics cards up to 410mm in length and CPU coolers up to 165mm in height.
