The flagship Midi Tower gaming case from the premium Light Base line, presented on the market by the popular brand be quiet!, serves as a platform for creating unique systems with complete freedom in choosing cooling components. The model comes without pre-installed fans, providing enthusiasts with the opportunity to realize their own vision of a cooling system. Massive dimensions of the case and E-ATX support provide space for the most ambitious projects. The be quiet! Light Base 900 DX case retains the key features of the series — instant transformation between standard, inverted, and horizontal orientation through movable feet.

The three-meter ARGB strip with 172 LEDs creates an impressive glow through the panoramic glass panels at the front and side. Ten fan mounts supporting 140mm models in all positions ensure maximum cooling configuration flexibility. Exceptional liquid cooling capabilities include simultaneous installation of two massive 420mm radiators on top and bottom plus a 360mm radiator on the side — a configuration not available in most cases. Removable brackets for radiators simplify installation outside the case. Two built-in ARGB and PWM hubs with 12 connectors make it easier to connect numerous components. Graphics cards up to 495mm long and CPU coolers up to 190mm high are installed without restrictions. The flexible graphics card holder works in any orientation. Support for motherboards with reverse connection creates a perfectly clean appearance.
