They even give you a extension cable to connect CPU power because the PSU is a long way from the top of the mother board. I also like the fact that you can install the PSU on either side of the case, I needed to use this option because I installed a radiator on the lower part of the case and being...

Everything

The price; but I guess you have to pay for quality

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.

I felt thou it lacked the quality of the 800D, i mean the motherboard tray plus the grommets felt a little bit flimsy compared to the 800D

So if you've not heard about the new Obsidian what rock have you been hiding under? It's been all over the web since it first got seen properly at CES. This does mean this is the replacement for the 800D, which when first released and still to this day a case that we were not and are not, all that...

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

Corsair's new flagship, the Obsidian Series 900D is a huge case, but also a case with huge possibilities. Apart from the models of a few specialty manufacturers, there are few competitive products.

able to accomodate HPTX motherboards and dual power supplies; plenty of room for CPU coolers; expansion cards; cable management; room for five coolers and fifteen fans; modular HDD cages provide for great flexibility; tool-free installation of optical drives; 3.5-inch hard drives; expansion cards,...

ex factory cooling performance and noise level; modification of the case can be time-consuming; no second recess for cooler mounting on dual-socket motherboards

saw a few reviews on it and they are right. Tons of room easy to work in. Plenty of room for water cooling if you want to do that crazy amount of drive storage

its LARGE tons of room 3 hot swap bays (internal) drive bays can be configured (stack as you want) cable management is great I can put 2 480 radiators and a 240 or even a 360 if I wanted to loose all the from drive bays Its a custom water coolers dream

did I say its LARGE and a little pricey you wont transport it to a LAN event NONE as long as you dont want to take it anywhere

if you want a case that has you wondering "what else can i fit in here, it looks kinda empty" then this is the case for you! this case makes even large cases look small, i went from an antec 1200 and that now looks tiny, there is enough hard drive enclousures to house enough data for any server...

One company that's relatively new to the case scene and has yet to offer up a case that we'd consider primarily water-cooling focussed is Corsair. However, it has been an ardent supporter of water-cooled PCs and strives to offer radiator mounts in all of its cases.
