A LOOK THROUGH THE DARKMIRROR
Showing off your rig through a smoked front panel is something you didn’t know you needed. The DarkMirror front panel enriches the contrast from hardware lighting, creating a picturesque display of the internal components. To cool gaming systems built inside, mesh ventilation is found on the entire length of the front panel’s sides, ensuring that the three included ARGB fans are fed with a considerable amount of air.

If you’re thinking about thermal upgrades, the MasterBox MB520 ARGB supports up to seven fans and front and rear liquid cooling for high-demand builds. Paired with a tempered glass side panel and additional top ventilation, your build can look, and play, exactly as you dreamed it would.
