THE OBSIDIAN 900D EXTERIOR
Several parts of the case are wrapped inside sheets of plastic so once you finally get it out of the box it will take you a couple of minutes to remove all of them.
Design-wise the 900D is nothing really special (like the 800D) and in that aspect i do prefer the Cosmos II by CoolerMaster, however when it comes to interior space the 900D is simply superior.
To showcase just how large the Obsidian 900D is we placed it right next to one of the latest midi tower cases to hit the market the Enermax Fulmo ST.
There's a huge window on the left side panel (in a way i think i like the side window of the 800D a bit more) and what seems a large compartment right beneath it.
There are actually two such compartments (one on each side) that open up by just pulling this small lever at the top.
These panels are actually perforated in their interior and also come with air-filters that attach themselves onto the panels via magnets placed on all their sides.
Getting at the front of the Obsidian 900D we see that Corsair has once again used brushed aluminum for the fascia.
Unfortunately with the amount of plastic Corsair dresses the fascia to ensure it doesn't get scratched (or the bay doors don't open and break) during shipping it's inevitable that some pieces (or glue) will remain. Anyways as you can see the 900D comes with four 5.25" drive bays (to be honest with you i would like at least 5).
The company logo is printed at the lower section of the front fascia.
Although it seems like the 900D has a total of five 5.25" that's not the case since the top one opens up to reveal the I/O which includes 4 USB 2.0 ports, 2 USB 3.0 ports, the reset button and the usual microphone and headphone ports.
The entire lower section of the fascia is removable and right behind it we see a large air-filter in front of three AF120L 120mm fans (you can place up to a 360mm radiator in this area).
Taking a look at the top we see that it's also perforated and according to Corsair you can install either 4x120mm or 3x140mm fans beneath it (or up to a 480mm radiator).
At the rear we see a large perforated space at the top, an AF140L 140mm exhaust fan, 10 PCI expansion slots and the PSU area.
What's quite impressive is that the PSU area has space for up to 2 power supplies placed vertically (or one if you choose to mount a radiator on one of the two sides).
Another great feature of the Obsidian 900D is that both side panels are not attached onto the main chassis via screws but via a latching mechanism that works by pressing these buttons.
Aside the tall feet there's nothing really worth mentioning about the bottom of the 900D.
