GAMING ON WIDE-OPEN THROTTLE

The MasterBox MB311L ARGB is a Micro-ATX airflow PC case pre-installed with two ARGB fans and made to be built with the latest gaming hardware. The front panel’s façade is made entirely of Fine Mesh, placed between two honeycomb vents on either side to maximize airflow. Since running the latest games, smoothly, means keeping the latest hardware efficiently cooled, top panel ventilation offers the option to add even more cooling hardware—if nothing is mounted, the top panel acts as passive ventilation.

The internal layout was engineered for a high compatibility for the latest gaming hardware while also accounting for future upgrades. Following in the principles of the award-winning MB Series, versatility is paired with presentation to ensure that any gaming system built inside the MasterBox MB311L ARGB looks as good as it performs.

FINE MESH FRONT PANEL

Mesh ventilation and upgrade capabilities ensure the latest performance gaming systems can be efficiently cooled.

MESH INTAKES

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

DUAL ARGB FANS

Two pre-installed 120mm ARGB fans can be managed by the motherboard, and connected by the included splitter, to create a comprehensive ARGB lighting system.

OPTIMIZED AIRFLOW

Airflow is optimized by a collaboration between the Fine Mesh front panel, additional mesh intakes, top panel ventilation, and rear exhaust.

TEMPERED GLASS SIDE PANEL

Hardware, custom-loop cooling, and the pure pride of the builder is shown in panoramic view through an edge-to-edge tempered glass side panel.

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 a total of six 120mm fans and front, top and rear radiator placement ensures that you don’t have to compromise on performance.

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.

ARGB CONTROLLER​

​The small ARGB Controller is a mini-sized controller that allows your Addressable RGB such as fans and LED strips to be powered and controlled even in PC systems without an A-RGB capable motherboard.​

The controller comes with 14 lighting presets to make full use of the Addressable LEDs in the system and also allows to be completely switched off by long pressing its button.​

It is also possible to attach any external 2pin button to it to be able to switch presets without having to open the system. For ease of use, Cooler Master allows the RESET button to be optionally connected to the controller and used as an external ARGB preset switch button.
