Product details

Every element of the MasterBox MB400L has been developed from an elegant palette. With a brushed finish, subtle color tone, and the minimalist Cooler Master hexagon, this Micro-ATX PC case enhances both gaming setups and workspaces while accommodating the latest hardware. The high style complements the high upgradeability with front, top, and rear ventilation, offering additional mounting options for future cooling component upgrades. When an optional RGB or ARGB fan is installed behind the front panel, the Cooler Master hexagon on the front panel is illuminated. In total, up to 6 fans can be mounted simultaneously to ensure that even the most demanding setups stay cool under heavy load.
