be quiet! Dark Base Pro 901 Full Tower Gaming Case

The Dark Base Pro 901 delivers professional-grade flexibility for enthusiast PC builds. This full tower case features dual configurations with interchangeable top covers and front panels—switch between silence-optimized or performance-focused airflow depending on your needs. All panels are included with user-friendly mounting systems.

Silent Wings 4 PWM Cooling System

Three pre-installed Silent Wings 4 140mm PWM fans provide exceptional airflow with minimal noise. The silence-optimized fan blades and funnel-shaped frames deliver high static air pressure at just 29.3 dB(A) at full speed. Each fan operates at 1900 RPM, moving 78.4 CFM while maintaining virtually inaudible operation. The 300,000-hour lifespan ensures long-term reliability.

Exceptional Component Support

The Dark Base Pro 901 accommodates radiators up to 420mm in the front, with support for E-ATX, XL-ATX, ATX, M-ATX, and Mini-ATX motherboards. CPU coolers up to 190mm, graphics cards up to 495mm, and PSUs up to 288mm fit comfortably. The case supports up to 16x 2.5" drives and 7x 3.5" drives with included mounting hardware.

Inverted Layout and Modular Design

An intuitive rail system enables easy conversion to inverted layouts. Detachable top and front brackets include an integrated fan hub and pogo pin connectors for simplified radiator and fan installation. The flexible VGA holder prevents GPU sag on heavy graphics cards, while dual cable bars organize internal wiring behind the motherboard tray and within the VGA holder.

Premium Build Quality and Features

Constructed from SGCC steel, aluminum, and ABS plastic, the case measures 604 x 254 x 539mm and weighs 16.3kg.
