FOR POWER-HUNGRY MATX BUILDS

The MasterBox MB311L is a Micro-ATX airflow PC case made to be built with the latest gaming hardware and ready for future upgrades.  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 looks as good as it performs.
