We are going to start off installation with our motherboard. Since the Dark Base Pro 900 is such a large case our motherboard goes in no problem at all. Simply secure it with screws and you are good to go from there. After your motherboard is installed it is probably a good idea to connect all of the cables to the headers on the bottom part of your board. As you can see we have plenty of room to do this.
Hard drives are next. We are going to be installing both 2.5-inch and 3.5-inch drives. First up are our 2.5-inch solid state drives. You simply place them inside the cages and secure them in the top and bottom using screws. Remember each cage supports two drives. Next is our 3.5-inch drive, you slide it into the cage and secure it on both sides with screws. As you can see there is sound-dampening grommets installed already. Now take the cages and simply slide them back into the backside of the case. One thing I noticed with our second solid state drive is that one of the thumbscrews is right under it, this means you will not be able to use a 90-degree SATA cable here.
To install your power supply you are going to want to remove the power supply bracket from the case. Once removed install your power supply and then take the whole bracket, power supply and all and place it back in the case. It goes in quite easily and sits right on the pads inside the case.
The light strips are not pre-installed, so you are going to need to install them if you want to use them. I decided to mount one in the front of the case and the other at the top. Once installed make sure you connect them to the hub on the backside of the case.
Our last part of installation is our graphics card. It easily fits in no problem with plenty of clearance between the end of the card and the hard drive cages. If you happen to have some massively long card you can always remove one or two of the drive cages you aren’t using. After I installed my graphics card I did notice that you could see a lot of wires under the motherboard and by the power supply. This case could really use a power supply cover.
Wiring the rest of the components up was pretty easy and those two holes you are required to wire everything through on the backside of the case actually work really well and make organizing cables easy. I really only needed to use one of the included velcro ties. If we go around to the main side of the case we have a very clean build, although all of those cables below the motherboard are sort of an eye-sore, again a power supply cover would solve this.
When you power on your system you’ll see that the LED strips light up the inside of the case pretty well. The power button on the case also lights up as well.
The light strips are controlled by the button on the front of the case. You can switch between red, green, blue, orange, white, or turn the lights completely off.
