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
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.
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.

Have you ever thought of trading in your old smartphone?
Recycling your phone is a great way to help the environment and earn some extra money, and Clove Technology offers a recycling programme that pays you for your old phone(s)!
So if you're about to buy a new phone from us, or you've recently bought one, why not sell us the handset you no longer need?
How much will you offer for my phone?
That depends on its age and condition. More recent phones generally have a higher value than old ones, but other factors can affect value. These include if the phone is working or not and its network lock status. Fully working phones with an unlocked network status will command a higher value if they are in good condition.
We pledge to beat the major recycling services operating in the UK on the price they offer for your
