be quiet! Dark Base 901 (Full-Tower E-ATX Support/Tool-Free Tempered Glass/3x Silent Wings 4 Fans Included/Premium Silent Flagship) Review
If you're comparing the be quiet! Dark Base 901 to the pricier Dark Base Pro 901, the difference comes down to a few premium touches, not the core design.
Both share the same modular, tool-free full-tower shell with three Silent Wings 4 fans; the standard 901 drops the Pro's extra fan controller display and a couple of finishing touches to land at a lower price.
Modularity
Drive cages, the PSU shroud, and even the top panel unclip without tools, so the interior reconfigures around E-ATX boards, extra radiators, or extra drive storage depending on what the build needs. Silent Wings 4 fans are be quiet's quietest stock fans by a good margin.
Comparison to Alternatives
It sits directly below the be quiet! Dark Base Pro 901 already in our catalog on price while keeping the same chassis and fans, and offers far more room than the be quiet! Silent Base 802 for E-ATX boards and big radiators.
