Cooler Master MasterBox 540
The Cooler Master MasterBox 540 Midi Tower PC case is the perfect foundation for building gaming rigs and powerful workstations. Its standout feature is the Ether-design front panel, which uses a transparent face and ARGB backlighting. The steel frame, complemented by a tempered glass side panel, provides plenty of space for motherboards up to E-ATX format. Users can easily change the colour schemes using the included controller or synchronise the LEDs directly with the motherboard software for a unified system look.
