Flimsy parts for a heavy case


Received the case today. The box was not damaged but it apparently was shipped upside down. Many of the 3 1/2 bay retainers had come out, along with their hinge pins. I found all but one retainer/pin set. (It's pretty hard shaking this case like a...


Some really cheap components in an otherwise massive case

That whole are on the back were video card screw in should be all steel , I'm I can literally bend with my hand . Other than that, great PC case!

Lots of space, wide case also beautiful large side window ; Great air flow

The io, we're video cards stii, that aluminum to week, it bends! !! I'm running 3 gigabyte 980s gtx and I'm noticing some sagging on the video cards

Big, well equipped ; Almost perfect

The hard drive carriers are terrible ; Whoever approved them should be tarred and feathered


Consumer review by:

very big!


I love the case it works great for everything i need it for!

Big if you need the space for cooling ; Very sturdy

I have one issue with the case witch is not that bad the brackets for the HD bays are plastic only flaw i think

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...

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,...
