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

Mammoth case marred by quality/customer service issues


Had the case arrived without such irritating aesthetic and functional issues, I'd wholeheartedly recommend this case to other looking for a case of the size. Even with the issues I've listed above, I'd likely still recommend this case if Corsair...

To say that this case does not lack for room to upgrade would be a considerable understatement ; Subjectively, the clean and uncluttered lines relative to many other cases on the market make this case refreshingly attractive

Upon freeing the case from the box, I noticed the following within minutes of inspecting the case ; The release button for the left side panel was stuck in the depressed position. With some difficulty, I managed to resolve that particular issue myself...

one big frigging case for sure!


I think with a case this large and considering the total weight of a finished machine I think casters would be an appropriate option.

This sucker is HUGE! Would be perfect for liquid cooling of if you have the need for a crazy high number of HDDs (9 expandable to 15!) ; Case arrived in perfect condition, not a scratch or dent. I have received cases in the past that suffered from poor...

While I did use a corsair H100I cooler for the CPU, I rely on fans to a large degree for keeping the GPUs cool. This case is huge but air flow appears to be not well thought out. A clean flow directly over the PCI cards would be nice to see. It is...

Best Case Ever!!!!!


Most people who right reviews on newegg either have no clue what they are talking about or they had a rare issue. If you are going to buy a case just make sure the manufacturer is trusted like corsair or nzxt and do not worry about reviews to much...

I am not going to get into details because if you want this case you probably have some experience and you know the features it offers. Everything about it is awsome!!!! It works like a beast for water and air cooling

The front aluminum came a little bit dirty but it was really easy to clean off ; The expansion slot is really hard to reach if you have a big gpu
