be quiet! Dark Base Pro 901 (Full-Tower E-ATX Support/Modular PSU Cover/Premium Silent Design/Flagship) Review
The Dark Base Pro 901 is be quiet!'s current flagship full tower, combining the brand's acoustic engineering with premium build materials and modular internal components aimed at high-end, no-compromise builds.
Tom's Hardware covered the Dark Base Pro 901's launch as a genuinely flagship-tier release, with premium materials and finishing that go well beyond be quiet!'s mid-range lineup. The 495mm graphics card figure applies with the HDD cage removed; with it installed, be quiet! lists 350mm.
A True Flagship, Not Just a Bigger Case
Tom's Hardware covered the Dark Base Pro 901's launch as a genuinely flagship-tier release, with premium materials and finishing that go well beyond be quiet!'s mid-range lineup.
Modularity Meets Acoustic Engineering
A modular PSU shroud and repositionable internal components let buyers reconfigure the interior for different build priorities, all while retaining be quiet!'s dampened-panel approach to quiet operation.
Comparison to Alternatives
Against the be quiet! Silent Base 802 already on this site, the Dark Base Pro 901 sits above it as the brand's true flagship, with E-ATX support and more premium materials at a higher price. Against the Cooler Master HAF 700 covered in this batch, the Dark Base Pro 901 prioritizes quiet operation and premium finish over the HAF 700's maximum-airflow, RGB-forward approach.
