Characteristics

INTERCHANGEABLE TOP AND FRONT

The best case in any situation

Whether you prefer a virtually inaudible or an extremely performant case: Dark Base Pro 901 is the perfect choice. Dark Base Pro 901 features a silence-oriented and performance-optimized solution for the top and the front. All panels are included, and a user-friendly mounting makes
switching a breeze.
 

MAXIMUM USABILITY

For professional and casual use

Dark Base Pro 901 offers all functions enthusiasts could wish for in a high-end case. Among them is a detachable top and front bracket with included fan hub and pogo pin connector for a comfortable installation of radiators and fans. Even an inverted layout can be done easily thanks to an intuitive rail system. Numerous cleverly integrated solutions make handling extremely easy. Dark Base Pro 901 can be deployed without the hassle of additional screws and small parts, creating the optimal case for any build.

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.

"Dark Base Pro 901 is the climax: The case's maximum versatility and performance is rounded up by new characteristics that have never been featured in a be quiet! case before."
