PC Case Cooler Master MasterBox 540 Desktop Black, Transparent

The Cooler Master MasterBox 540 is a desktop PC case with a black DarkMirror front and a full-width iridescent ARGB Ether front panel. The front features customizable ARGB lighting strips behind a transparent façade and includes a controller that can sync lighting with compatible motherboards. The top panel is fully removable for easier routing and installation of large radiators and fans, while a tempered glass side panel provides tool-free access secured by pins with an optional screw for extra fastening. The case supports multiple cooling configurations and a ventilated power supply shroud for flexible PSU orientation.

Advantages

The ARGB Ether front panel offers an automotive-inspired diffuser and integrated lighting structure for a distinctive illuminated front. Standardized ARGB connector and included controller allow both software and hardware control with preloaded lighting presets and a routed RESET/ARGB button. A removable top panel and screwless tempered glass side make assembly and component access simpler, and the breathable PSU cover enables installation of actively or passively cooled power supplies.

How to use

Install the motherboard and components according to the motherboard and component manufacturers’ instructions. Connect the included ARGB controller to the front panel connector or to a compatible motherboard ARGB header to manage lighting. Remove the top panel when fitting large radiators or routing tubing and use the tempered glass side panel pins for quick access during assembly; secure with the optional screw if additional retention is desired. Place the PSU in the shroud and choose fan orientation based on cooling preference, ensuring ventilation openings are not obstructed.

Recommendations

For best compatibility, verify motherboard ARGB header type before connecting; use the included controller if your motherboard lacks a compatible header. When installing liquid cooling radiators, remove the top panel first to improve clearance and routing. Ensure the PSU ventilation aligns with the chosen orientation and allow clearance for cable management behind the motherboard tray.
