be quiet! unveils massive Dark Base Pro 901 chassis supporting inverted motherboard layout

Build it however you want.


be quiet! has showcased its Dark Base Pro 901 chassis with an emphasis on customisability and compatibility. Club386 is on hand at Computex to reveal all the details.

Marketed as a successor to the popular Dark Base Pro 900, this new flagship is yet again representing the epitome of flexibility in be quiet!’s lineup thanks to an inverted layout that allows the motherboard to be installed upside down for those who prefer having a right-sided view of their hardware, all while reducing the number of required screws and small parts.

The Pro 901 appears to cater for a cleaner and roomy airflow-friendly approach capable of housing up to E-ATX motherboards, 420mm radiators in the front plus 360mm in the side and top, a total of 11 120mm fans or 10 140mm ones, and two 3.5in plus six 2.5in drive spaces with the possibility for having more (5+10) using addon cages. Note that a solution for installing a 5.25 drive is also still available at the bottom, if needed.

The lower compartment is big enough to hide any desktop PSU format, now with an improved and easier installation from the back, no longer requiring an offset like the older Base 900. On top of said compartment sits a height-adjustable GPU anti-sag device marrying functionality with clean aesthetic by hiding the cables while supporting the card. The latter can also be installed in the inverted board layout. Nice.

Out of the box, the case comes with three pre-installed 140mm Silent Wings 4 fans speed-adjustable via the frontal touch-sensitive fan controls. Talking of which, the front I/O also carries four USB 3.2 Gen 1 Type-A ports alongside a single USB 3.2 Gen 2 Type-C and two audio jacks. Those who like RGB lighting are not forgotten either as the Pro 901 includes ARGB LEDs with two dedicated touch buttons for choosing the colour and mode. A wireless smartphone charger with 15W and fast charging support is also present.

The Dark Base Pro 901 chassis will be available this June shortly after Computex for $299.90 / €319.90 MSRP.
