GAMING ON WIDE-OPEN THROTTLEThe 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
Cooler Master’s 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.
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

Excellent value.
The instructions were pretty easy to follow. I appreciate that there was an extra screw of each size provided, just in case. I wish there had been clearer indications on how to handle the cord or the included light. I ran it down the inside and mounted the switch on the inside of the display shelf.
I bought the white variant; however, beacause I am not fond of black furniture and tend towards bright colors, I used blue spray paint to cover the black metal and make the piece better fit my decor. A white with white option would have been ideal, but now I have a unique piece so it all works out.
The value for the price is excellent. It is a large, sturdy piece that should prove functional for years to come. I am considering purchasing a second one for my husband's gaming space.

Looks great
The assembly instructions were clear and well done. Parts are all well made and holes were precision drilled. Very happy with this product.
It is heavy enough that mounting it on the wall is a chore. I strongly recommend you measure the holes and mark using a level and install your anchors - I used the white screw-in ones.
The control app for the LED strip doesn't have a good rating. I have to tap it a few times to get it to engage but it works.
