This case has room for everything, can be expanded for 15 hard drives while still having room for 4 Blu-Ray drives! New, it's a bit expensive, but if can find it used for $220 or less, just buy it. Any missing components are relatively inexpensive to buy directly from Corsair.

D900 best product with 16 expantion slots. Easy tooless entry makes installation of hardware a snap. Being able to install 2 power supplies, as big a motherboard as you can buy is quite the ultimate pro case on the market.

Upgrade from the 600c, loads of room for everything, including dual water loops and twin 420 rads and still more room. EXELENT.

Excellent case. I've got two and have had ZERO problems. For those whining about the HDD trays, all I can say is that I've had no issues at all with them on either case. And all the bays are in use, and I've done multiple HDD swaps with no issues.

Lots of room for many / large video cards and drives Excellent build quality Nice looking Dual power supply possibility No tools needed to change drives; open case; etc

It's heavy

excellent packing AAA+ service

Corsair likes to make cases, I think we know that much for sure by now. I mean, they have designed something on the order of 13 different chassis , not including color variations. The very first case Corsair shipped was the Obsidian 800D and at the time it was massive, just down right big.

During CES in January of this year Corsair were happy to show reasonably final samples of the 900D case, a follow up to 2010's 800D. The 800D was a hugely impressive case for its time and since reviewing that we can only think of a couple of models which come close to competing in the high end of...

The Corsair Obsidian Series 900D MSRP is $349.99. While this may seem like a lot of money, the price is definitely in-line with other cases in its class. We know this may be a sticking point for some, but we honestly think this chassis is worth the asking price.

The Corsair Obsidian 900D is certainly a beast of a case. If you're looking to install insane amounts of water cooling, massive motherboards, graphics cards, and to simply have the room to expand your system as needed without the concern if it will fit or not, there will be few if any that will meet...
