Pictures don’t do justice to the enormity of the Corsair Obsidian 900D. There is an absolute reason that Corsair has nicknamed the 900D ‘Godzilla’. It measures an impressivex 649.6×691.6x252mm (25.57″x27.23″x9.92″inches), the Corsair Obsidian 800D measured 609x 609×229 mm (23.98″x23.98″x 9.02″). The 900D is larger on every dimension by at least an inch! What I like about the Corsair Obsidian 900D is the pure simplicity in style. It doesn’t have any flashing lights, cheap molded plastic designs, or anything that doesn’t have a purpose. Nor does it leave anything to the imagination when it comes to the parts used and your build skills. The side panel of the 900D measures 18.5″x15.75″. The window and side panel wont hide anything from view. Below the side panel is a panel that can be folded out for access to some of the parts hanging out on the bottom of the 900D Super Tower chassis. We’ll look at that soon though.

Taking a look at the opposite side of the Corsair 900D its a little less exciting that the windowed side. Though we do have the same door down at the bottom of the chassis.

Taking a look at the back of the Corsair Obsidian 900D Super Tower chassis, there are a couple of things that jump right out at us. First and foremost is the expansion slots, the 900D is equipped with ten expansion slots! This is one of the improvements over the 800D that came equipped with only seven expansion slots. Now we can easily set up a quad-sli/quad-CrossfireX with four dual slots graphics cards. The second most notable (at first glance) feature is the ability to run dual power supplies or simply choose where you want your power supply mounted.

Much like the Corsair Obsidian 800D, the 900D side panels are released by pressing the buttons in the corners. This push button technique makes removing the doors incredibly simple to do. Once you depress the button the top of the door can swing out and you can then lift it off of the chassis.

The front of the Corsair Obsidian 900D Super Tower continues the understated design and simplicity that I like about this case. What looks like it might be the top 5.25″ bay is actually the front panel behind that door. The power button is visible at top center. Below the front panel door we have four 5.25″ expansion bays. The panel that carries the Corsair badge can be removed to reveal three 120mm Corsair A1225L12S fans.

The top expansion bay of the Corsair Obsidian 900D isn’t an expansion bay at all. Turns out that this is actually a door to cover up the front panel. To open the door to reveal the front panel simply press and release on the upper left hand corner.

Once you have opened up the door to the front panel, first thing I noticed was the number of USB ports that Corsair has included here. On the left we have a pair of SuperSpeed USB 3.0 ports, and four USB 2.0 ports on the right for a grand total of six ports. To the left of the USB 3.0 ports is a pair of 3.5mm audio jacks for microphone and headset. Dead center of the front panel there is a small reset button while the power button is the larger bar just above it.

Removing the panel is as simple as pulling it away from the chassis. Between the panel and the fans we have a removable dust filter that releases by depressing and releasing the two top corners.

The three Corsair A1225L12S fans are set up as an air intake, pulling cool outside are into the Corsair 900D. The Corsair A1225L12S fans are rated for 32.95 CFM at 1200 rpm.

There isn’t much exciting on the bottom of the Corsair Obsidian 900D Super Tower. In each of the corners though, there is a nice heavy duty rubber foot to protect the surface that you set the system on.

The entire top of the Corsair Obsidian 900D Super Tower chassis is an air filter. Once this is removed we can scope out what type of cooling can be run up here.

We’ve now seen how impressive the outside of the Corsair Obsidian 900D Super Tower is, Let’s move to the inside and see whats hiding on the inside!
