PC CASE

Palette & Brush
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.

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.
