Each element of the MasterBox MB400L was created from an elegant palette. With a brushed finish, subtle hue, and the minimalistic Cooler Master hexagon, this Micro-ATX PC case decorates the gaming setup and workspace while also being able to house the latest hardware.

High style embellishes high upgradeability with front, top, and rear ventilation, offering additional mounting options for upgrading cooling components in the future. If an optional RGB or ARGB fan is installed behind the front panel, the Cooler Master hexagon will also be illuminated on the front panel. A total of 6 fans can be mounted simultaneously, ensuring that even the most demanding builds can stay cool under heavy use.
