be quiet! LIGHT BASE 900 FX White Full Tower (EAN: 4260052191781)
The be quiet! LIGHT BASE 900 FX White Full Tower is a premium showcase PC case engineered for high-end gaming and workstation builds where airflow, silence, and RGB presentation matter equally. Built from ABS, SGCC steel, and glass, this full-tower chassis delivers a clean white aesthetic with panoramic visibility and integrated multi-zone RGB lighting across the front and case fans.
Designed to handle today’s most demanding hardware, the LIGHT BASE 900 FX supports ATX, E-ATX, and micro-ATX motherboards, massive graphics cards up to 495 mm, tall air coolers up to 190 mm, and PSUs up to 225 mm. The spacious interior and smart layout make it ideal for flagship GPUs, large power supplies, and complex cooling setups without compromise.
Cooling flexibility is a core strength. The case comes pre-installed with 3× 140 mm side fans and 1× 140 mm rear fan, all with fan speed control, and supports additional fans on the top and bottom. Extensive liquid-cooling support allows multiple radiator placements, making it suitable for powerful AIOs or custom loops. Integrated anti-dust filters help maintain optimal airflow and long-term system cleanliness.
On the usability side, the front I/O provides modern connectivity with USB-C (USB 3.2 Gen 2), USB-A ports, and audio jacks. Dedicated RGB control, reset, and power buttons give direct access to lighting and system functions. Developed by be quiet!, the LIGHT BASE 900 FX is tailored for builders who want a silent-focused yet visually striking full-tower platform with uncompromising component compatibility.
