be quiet! Dark Base Pro 900 Overview
The be quiet! Dark Base Pro 900 is marketed as a mid-tower computer case that features water cooling support without sacrificing air flow and without sacrificing numerous configuration possibilities. Airflow is achieved through the fan mounting options. With this case, you can have; 3 x 140mm fans or 3 x120mm fans (w/o ODD cage) in the front, 2 x 120mm or 2 x 140mm fans on the bottom, and 3 x 140mm or 4 x 120mm or 1 x 180mm fans in the top. All intakes are filtered, as well as the top ventilation.
The front of the Dark Base Pro 900 features a reversible brushed aluminum door, filtered side intakes on each side of the bezel and a small be quiet! logo. The brushed aluminum is a bit of a fingerprint magnet though, so if you’re a little OCD about these things (as I am) then you’ll find yourself cleaning it often after you build the computer.
The Dark Base Pro 900 also features a wireless Qi charger! That’s right, you can charge your cell phone wirelessly by just simply placing it on top of the case. The front I/O ports include 2 x USB 3.0 ports, 2 x USB 2.0 ports, microphone jack, headphone jack, an illuminated power button, a reset button, and an HDD status light. The front IO integrates seamlessly with the Qi charger and the top panel of the case.
The left side of the Dark Base Pro 900 features a filtered intake hidden behind the be quiet! logo. The cover is removable, revealing two 120mm fan mounting locations. Not sure why you’d mount two fans on the back of the motherboard, but it’s orientation in relation to the rest of the door indicates it could be used for additional HDD cooling if needed. You’ll also notice that there is ventilation running across the bottom, front bezel, and top of this case. These vents are filtered and of adequate size.
When you look above at the rear of the Dark Base Pro 900, what do you see? Well,what you won’t see is PSU mounting holes. The Dark Base Pro 900 utilizes PSU passthrough, this allows you to customize the height of motherboard tray inside the case. If you look closely, you’ll see 3 panels below the pci slots, two small, and one larger with a power button and power cord port. All three panels are removable, and the two smaller panels can be moved to the top, thus lowering the motherboard tray. The rear features plenty of ventilation, a 140mm/120mm fan/radiator mounting location (140mm fan pre-installed) and vented pci slot covers. I would have liked to seen some reservoir slits cut into the mesh adjacent to the pci slots, like that of the Phanteks Evolv Tempered Glass case.
Because of all the ventilation on the sides, top, and front of this case, there was no need for any vents on the bottom of the case. The feet are removable, this is accomplished by removing the bottom section of the case. Remember I said this thing is modular right?
