SILENT WINGS 4 PWM FANS

3 pre-installed fans for maximum airflow
Features like the silence-optimized fan blades and the funnel shaped fan frame make Silent Wings 4 140mm a fan that makes no compromises between virtually inaudible operation and high performance. Its extraordinary air pressure significantly increases the cooling performance of
Dark Base Pro 901.

THINK BIG

Generous dimensions for radiators up to 420mm
With its remarkably large dimensions, Dark Base Pro 901 sets no limits on creativity. The front can fit a radiator of up to 420mm and additional fans can be installed throughout the case, even on the side panel.

FLEXIBLE VGA HOLDER AND CABLE BARS

For a neat interior
The VGA holder of Dark Base Pro 901 is very versatile and prevents GPU sag even with heavy graphics cards. 2 cable bars, one located inside the VGA holder and the other next to the motherboard tray, hide the cables inside the case. No matter how big or numerous the components built in Dark Base Pro 901 may be; with such clever features the result always makes a
good impression.

ARGB LIGHTING

And convenient features
Dark Base Pro 901 features ARGB lighting on the front and the PSU shroud: The lit-up areas are chosen consciously to ensure the case remains elegant with subtle illumination. The light and fan settings can be conveniently controlled via touch-sensitive buttons on the I/O panel. A wireless charger for Qi enabled devices perfectly rounds up Dark Base Pro 901.

TEMPERED GLASS WINDOW

A perfect view inside your PC
The high-quality, fully-windowed side panel offers a perfect view of the components inside your case. The window is made of tinted and tempered glass with black painted edges.
