THE OBSIDIAN 900D INTERIOR

Corsair uses quite thick side panels but as expected (due to the side window) they don't feature any kind of noise-absorbing coating.

The interior is massive so in a way i do understand the question Corsair asks on the box.

All four 5.25" drive bays use tool-less locking mechanisms which may not look pretty but they are quite sturdy.

There are three removable drive cages (you can stack them all together vertically, horizontally or as seen above) placed inside the 900D each able to hold up to three 2.5"/3.5" drives. To remove and rearrange them you will need to remove the screws found at the rear.

The lowest drive cage also features 3 hot-swap spots.

Now had this been an average midi tower i'd really be ok with the substandard drive trays used but since the 900D is the current Corsairs flagship case i really can't seem to figure out the why this happened. Now i do have to admit that these are very easy to use but I’ve seen better quality ones used with midi towers that cost 3 times less and at least for me that's a serious drawback.

There's plenty of space behind the mainboard tray to route even the thickest cables.

Corsair has also placed cable holders behind the mainboard tray to make cable management even easier.

An 8-pin EPS 12V extension cable is attached at the rear of the mainboard tray since naturally a PSU will have a hard time reaching over.

The mainboard tray has a large CPU cutout area and 8 rubber grommeted cable routing holes along with two "naked" ones.

Where Corsair has placed the AF140L 140mm exhaust fan you can also place a 140mm radiator. As for the perforated space that is mostly for show (although it should also provide the interior with some fresh air) since Corsair wanted to leave plenty of room between the top and the mainboard for people who would like to use large radiators.

All of the PCI expansion slots are secured in place via regular thumbscrews and as for the PSU area well Corsair had to do that for people who may also want to take advantage of the left/right radiator spots right past the compartment panels (up to 480mm radiators on the opposite side and 280mm on the side with the PSU).
