be quiet! Dark Base Pro 901 White Full Tower Gaming Case

The Dark Base Pro 901 White delivers professional-grade flexibility in a premium full tower chassis. Designed for enthusiasts who demand both silence and performance, this case features interchangeable top and front panels that allow you to switch between silence-optimized and performance-focused configurations without tools.

Dual-Configuration Design

Choose your priority: virtually inaudible operation or maximum airflow performance. The Dark Base Pro 901 White includes both silence-oriented and performance-optimized panels for the top and front. The user-friendly mounting system makes switching between configurations effortless, adapting to your specific build requirements.

Silent Wings 4 PWM Cooling System

Three pre-installed Silent Wings 4 140mm PWM fans (two front, one rear) deliver exceptional cooling performance at whisper-quiet noise levels. These fans feature silence-optimized blades and funnel-shaped frames that generate 78.4 CFM airflow and 2.36mm H2O air pressure while maintaining just 29.3 dB(A) at full speed. The included 5-step fan controller with dual PWM hubs provides precise control over your cooling setup.

Expansive Component Support

With generous internal dimensions (604 x 254 x 539mm), the Dark Base Pro 901 White accommodates E-ATX, XL-ATX, ATX, M-ATX, and Mini-ITX motherboards. Install radiators up to 420mm at the front, 360mm at the top or side, and graphics cards up to 495mm long with HDD cages removed. The case supports up to 11 fans total and features 190mm CPU cooler clearance.

Inverted Layout Capability

The intuitive rail system enables easy conversion to an inverted motherboard layout. Detachable top and front brackets with integrated fan hubs and pogo pin connectors simplify radiator and fan installation. The tool-free design eliminates the hassle of managing small screws and parts during assembly.

Premium Cable Management

A flexible VGA holder prevents GPU sag even with heavy graphics cards. Two cable bars—one integrated into the VGA holder and another beside the motherboard tray—keep cables organized and hidden. Multiple 2.5" and 3.5" drive mounting options (up to 16x 2.5" and 7x 3.5") provide extensive storage flexibility.

ARGB Lighting and Connectivity

Subtle ARGB illumination on the front panel and PSU shroud (24 total LEDs) creates an elegant aesthetic. Touch-sensitive controls on the I/O panel manage lighting and fan settings. The comprehensive I/O includes 1x USB 3.2 Gen 2 Type-C, 4x USB 3.2 Type-A, HD audio, and a 15W Qi wireless charger for compatible devices.

Tempered Glass Window

The fully windowed side panel features high-quality tempered glass with white-painted side bars, providing an unobstructed view of your components. Aluminum top cover and front panel construction ensure durability and premium aesthetics.

Noise Dampening Features

Insulation mats on the top, front, and side panels reduce noise transmission. Anti-vibration mounting for HDDs, fans, PSU, and motherboard tray further minimizes operational noise. Removable dust filters at the front and bottom protect components while maintaining airflow.

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 White is the perfect choice. Dark Base Pro 901 White 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 White 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 White 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 PWM White 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 White.

THINK BIG

Generous dimensions for radiators up to 420mm
With its remarkably large dimensions, Dark Base Pro 901 White 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 White 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 White may be; with such clever features the result always makes a good impression.

ARGB LIGHTING

And convenient features
Dark Base Pro 901 White 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 White.

TEMPERED GLASS WINDOW

A perfect view inside your PC
