Overview

The be quiet! Dark Base Pro 901 White is a flagship full-tower PC case that combines silent operation with extensive hardware compatibility. It comes pre-installed with three Silent Wings 4 140mm PWM White fans, delivering efficient airflow while maintaining whisper-quiet operation. The interchangeable top cover and front panel allow users to prioritize either maximum ventilation or near-silent computing. The intuitive touch-sensor I/O panel adds modern convenience, making this an excellent choice for high-end builds.

Compatibility Guide

This case supports E-ATX motherboards, as well as standard ATX, Micro-ATX, and Mini-ITX form factors. It offers ample space for large graphics cards, custom liquid cooling loops, and multiple storage drives. The power supply is mounted in a bottom compartment, ensuring clean cable management. With its generous interior dimensions, the Dark Base Pro 901 White can accommodate virtually any consumer hardware configuration.

Product Info

Positioned at the top of be quiet!'s case lineup, the Dark Base Pro 901 White is available through authorized retailers in Japan for approximately ¥54,000. The chassis is constructed from aluminum, steel, and tempered glass, finished in a clean white coating. Its dimensions (569mm wide, 610mm deep, 275mm high) classify it as a full-tower, yet the advanced noise-dampening features keep operation impressively quiet.

Best Use Cases

This case is ideal for silent PC enthusiasts who demand low noise without compromising performance. It also suits builders creating white-themed gaming or workstation rigs, as the clean aesthetic pairs well with other white components. The E-ATX support future-proofs the build for upgrades to larger motherboards. Additionally, the excellent cable management and tool-less drive installation make assembly straightforward for both new and experienced builders.

Things to Consider

The full-tower size requires significant desk or floor space. The case is heavy, so moving it after assembly may be cumbersome. White surfaces show dust and smudges more readily, requiring regular cleaning. While the included fans are excellent, users planning custom water loops should verify radiator clearances – the case supports radiators up to 360mm in the top and front. Competitors like Fractal Design and Corsair offer similar chassis, so compare features and aesthetics before purchasing.
