MasterBox MB520

The MasterBox MB520 focuses on aesthetics and showmanship with a fully transparent front panel. For rigs built with lighting as a concentration, the front panel offers to view components through the panel while having the aggressive intakes to ensure airflow.

The aggressive ventilation on the DarkMirror front panel cools the system while the ventilation on the top panel offers additional thermal support.

Building a gaming rig is a process that evolves in components over time. To align with the pace of technology, interior clearances have ample space to support future component upgrades. The chassis and PSU shroud are powder-coated in black to help compliment your build while the edge-to-edge transparent side panel shows it off.
