Product Description
Be Quiet! Light Base 900 FX – Elite Showcase ARGB Gaming Tower

Striking Visual Design for Ultimate Showcase Builds
The Be Quiet! Light Base 900 FX Black is engineered for PC builders who want their systems to shine from every angle. With fully windowed glass front and side panels, this case offers a panoramic view into your setup, making it ideal for showpieces with RGB components and advanced cooling. The large ARGB LED strip with 172 LEDs and included ARGB controller gives you total control over lighting effects, while the reversible layout allows you to switch orientations in seconds.
High Performance Meets High Capacity
Designed for elite configurations, the Light Base 900 FX features four pre-installed Light Wings 140mm PWM ARGB fans for balanced cooling and noise levels. It accommodates up to ten fans and three radiators simultaneously—including dual 420mm radiators and a 360mm side radiator—for extreme thermal performance. With support for E-ATX motherboards and the largest GPUs on the market, it ensures you’re future-proofed for any high-end component.

Unmatched Flexibility and Clean Build Experience
Whether you’re aiming for a vertical, inverted, or horizontal layout, this chassis delivers unprecedented modularity. A flexible VGA holder prevents GPU sag, and two integrated ARGB/PWM hubs simplify fan and RGB cable management. Compatibility with Asus BTF and similar backside-connector motherboards ensures a clutter-free aesthetic. With a tool-less interior, detachable radiator brackets, and expansive storage options, the Light Base 900 FX empowers builders with a streamlined and visually stunning PC experience.
