A Look Through The DarkMirror

The MasterBox MB520 ARGB is the optimum ATX gaming PC case for showing off component lighting while keeping systems cool. The DarkMirror front panel is smoked a shade darker to add sharper contrast to the pre-installed ARGB fans. On each side of the front panel, mesh ventilation spans from top to bottom to provide the interior with considerable airflow.

The front mesh ventilation works collectively with the top and rear ventilation to optimize airflow. With support for up to seven fans and front, top, and rear liquid cooling components, there is a high potential for both air-cooled and liquid-cooled builds. With a tempered glass side panel, ARGB fans, and a DarkMirror front panel, every build is properly displayed inside the MasterBox MB520 ARGB.


DarkMirror Front Panel – Shade light through the DarkMirror front panel for a sharper contrast of the ARGB fans.

Mesh Intakes – Large, mesh intakes on each side of the front panel provide considerable airflow to system.

ARGB Lighting System – Three pre-installed ARGB fans can be managed by either the motherboard or an included controller, connected by the included splitter, to create a comprehensive ARGB lighting system.

Certified compatible with: ASUS, Gigabyte, MSI and ASRock motherboards.

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.

Optimized Airflow Filtered ventilation on the top panel provides additional thermal support while also offering mounting options for future cooling upgrades.

Versatile Cooling Options – Support for up to seven 120mm fans and dual 360mm radiators on the top and front panel ensure that even the most extreme systems stay cool.
