Cooler Master MasterBox MB400L mATX

Brushed Front Panel

A brushed finish spans the entire front panel for an elegant and minimalistic design.

Hexagon Gleam

If an optional, illuminated fan is installed, the Cooler Master hexagon logo will capture light from the fan and emit a glow on the front panel.

Mesh Intakes

Large, mesh intakes span each side of the front panel to provide additional airflow to system.

With/Without ODD Support

Depending on preference, an ODD version of the chassis is available. If an ODD is not preferred, a cleaner appearance and more cooling options on the top and front panels are supported.

Adaptable Drive Cage

The drive cage is (re)movable, able to shift toward the front to accommodate for PSU space, backwards to provide additional radiator space, or even completely removed.

Versatile Cooling Options

Support for up to six fans and front, top, and rear radiator support ensure that performance is not compromised.

Room For Upgrades

Support for up to a 344mm graphics card, a 166mm CPU cooler, and up to a 325mm PSU in length provides room for upgrades to stay ahead of the game.
