MasterBox 520 design and cooling
The steel construction combined with a tempered glass panel provides a direct view of the installed hardware. The cooling system relies on three pre-installed ARGB fans at the front and one standard fan at the rear. Dust filters in all key areas prevent dirt from entering the interior.

The internal space accepts graphics cards up to 410mm in length and CPU coolers up to 165mm in height. Data storage positions include two 3.5" drive slots and three 2.5" SSD bays. The top I/O panel includes a USB-C port for fast data transfer and a standard USB 3.2 Gen 1 interface. An integrated ARGB hub makes it easy to synchronise the backlighting with other components in the build.
