Beastly watercooling case


I crammed two 480mm and one 240mm radiators in, all 60mm thick, in push. This case exceeded my expectations. Its the sharpest looking case I have seen.

Tons of room ; Looks sharp and powerful ; Lots of places to mount radiators ; Great price compared to other options

Looks funny if you put anything in the 5.25" drive bays

Spacious... but that's about it.


The cons HIGHLY outweight the pros, in my humble opinion. Replacing any PCI devices is borderline impossible. You can't get access to the screws that hold the PCI cards to the back panel because the rear/right pillar is the way. You'll bleed and hurt...

Lots of room ; Enough room to fit a small child ; You can fit all your gear in there, including desk and chair ; Looks pretty good ; Modular construction and Corsair sells replacement parts through their store. Super nice

Did someone actually use this case at Corsair ; PCI SCREWS ARE IMPOSSIBLE TO... SCREW ; Way too heavy ; It's large, nay, HUGE ; So many holes you can hear anything inside like it's outside ; Vents in the rear don't have any sort of filter ; Installing...

Not up to the marketing and hype. I purchased some Noctua fans to replace the stock fans; these are four pin PWM units. They may be brown but I can rely on their cooling my innards. I guess I will be changing my color scheme.

A lot of room for sure and looks good too. Layout and design are commendable as well. Good marketing and hype on the part of Corsair; got to give them props for that. Does sarcasm belong in the Pros section? Seriously this case looks great, lights up...

Flimsy parts and pieces everywhere. One of the plastic clips that is containing the wiring on the back broke as soon as I removed it; brittle describes it best. Be careful when opening the hard drive trays as the pins that are being used as hinge...

Saved By The Cave


Cavernous interior saves this case--expected more from a firm like Corsair--would have returned but too much time invested in populating this case.

Cavernous interior--very good interior layout overall

Drive bays belong in a $50 case, not a $300+ case, flimsy construction--top panel mounting design is a disaster--top panel seemed to be welded to the frame--finally popped free after MULTIPLE days of pushing here, pulling there and damage to case...

Corsair CC-9011022-WW


Though I am completely satisfied with this case, it is NOT for your average user, or even your average enthusiast. Don't buy this case if you are looking for bang for buck. Buy this case if you are looking to dump an obscene amount of money into an...

Biiiiiiiiig. This case is larger than your standard full tower by quite a bit ; Lots of mounting options for radiators ; Light construction makes the case surprisingly light

Expensive ; As others have mentioned, this case has relatively poor airflow. You need more than just the 4 fans that come with the case ; The case is so large that it is difficult for all of your cables to reach their intended locations. Consider...

Premium and Solid


If you need a big case, just buy it.

There's a lot to like about this case. I'll skip the obvious stuff. The one thing that I find that most cases fail to do is attention to detail. There isn't a spot in this case that isn't matching the paint. Some manufacturers will toss in a couple odd...

The cons might turn some people off. The case is huge. When I say huge, I mean if you've only owned mid-towers your entire life, then you have no clue how big it is. Its so large in fact, that it tends to warp its own frame. Its not a huge problem,...

nearly perfect


good size, features, design

just a little bit on the flimsy side, all things considered. you have to be pretty careful with the panels on the side near the bottom that fold open

Great tool for installing video cards & better fans


Size, flexibility, and design

Limited space requires WERA 8001 A ratcheting micro wrench with 50 mm PH1 bit to install thumb screws; total tool length is 2.125 inches and allows thorough thumb screw tightening for tall cards like EVGA classifieds ; Stock fans are loud and should be...

Overall, even with the issues of the hard drive holders, I'm still giving this case a solid 5 eggs. This is the best case I've never had the pleasure to work with and I'm glad I went with it.

Wowsers is this a big case. I was originally looking at getting the Corsair 800D for my new build, but since I wanted to run a dual loop system and wanted slightly bigger radiators for it, I went with the 900D instead. While I am rating the size of...

There is really only one gripe I have about this case and that is the hard drive holders. Why Corsair? Why did you have to make these things plastic ; In the regular bays, they feel flimsy after they are installed, but in the swap-out bays, they feel...

Almost big enough for 2 computers


Overall great case I love looking at it but it should have a few more features that should already come with the price tag.

It is the biggest case I've ever seen. It is nearly twice the size of my prior case the 600T. More room than you could ever dream of using

Cable management is sort of annoying, door panels are a pain to take off and fold down panels on the bottom are magnetized. No rolling casters either
