Inside the Dark Base 900 Pro




Once the tempered glass panel was removed, we get our first look deep inside of the Dark Base 900 Pro. Along with a bunch of things we are going to cover in detail, we also found the hardware as well as a box for the LED strips tied to the HDD cages.





Our first stop is at the front, all the way at the top, where we find a cage which houses a pair of 5.25" drives. This can also be removed to allow for water cooling in the front, and even ships with a bracket to aid in fan placement here.




The rest of the front of the chassis is taken up with these seven drive bays. While they will each hold one 3.5" drive, each of them will support a pair of 2.5 drives. All of them or some of them can be removed, and via holes in the frame closest to us, we can even switch sides with them.




After removing the top panel, discovering the QI charger and front I/O stay with the chassis, we can see the fan mounting options. There are many ways to hang fans and radiators, as well as slots for both 120mm and 140mm options.




The motherboard tray offers a large access hole and is clearly marked for various motherboard support. Not only can this be swapped to the other side, it can ride at three heights within the frame, and can also be used as a test bench, separated from the chassis.




The floor of the chassis starts with an internal PSU support bracket at the back. The PSU can rest on rubber pads placed on the floor, and there is an optional location or a fan just in front of it. If you remove the HDD cages, there is yet another fan location in front of that.




The expansion slots are held in with thumbscrews to make life easy, and we can see the third 140mm Silent Wings fan installed here. The wiring is not hanging down because it is already connected to the fan and LED controlling PCB in the back.




For now, this is the back of the chassis, where the motherboard tray and HDD assembly is currently mounted. There is 20 to 25mm of room for wiring, and to get around the frame supports, holes have been added to pass wiring through the parts too close to the side panel.




Moving in a bit closer, we can see the PCB which controls the RGB lighting and offers up with fan locations. The PCB can be run from a PWM signal or be set to run full speed. To the right, we see a way to hide a 2.5" drive, as there is a tray for it hanging there.




While the wiring may seem short, there is plenty to get them connected. In this group, we see the SATA power lead for the PCB and QI charger, the switch and LED connections, a native USB 3.0 connection, one for USB 2.0, and the longest of the group is for HD Audio connectivity.
