Features:

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 panels 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
Cooler Masters Fine Mesh design on the front panel is proven to provide proficient airflow while filtering out dust.

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 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.

Sickleflow PWM fans included
Newly Optimized blade design with updated curve that provides best balance between airflow and static pressure to take the heat away while remain extremely silence.
