2 out of 5 eggsNOT WORTH THE PRICE

Pros: 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 well and shows off your innards very nicely.

Cons: 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 replacements will fall out almost every time. One of the 120mm fans that came with case only spins around 600 rpm on a good day. You can literally see that it is spinning slower than the rest. The bottom doors along the length of the case are always falling open.

Other Thoughts: 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.

3 out of 5 eggsSaved By The Cave

Pros: Cavernous interior--very good interior layout overall

Cons: 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 paint--overall quality control suspect--top of frame bowed contributing to top panel removal troubles--documentation terrible!!

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

4 out of 5 eggs

Pros: - 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.

Cons: - 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 buying extension cables for your PSU and fans.
- Light construction makes some of the parts seem flimsy and won't take a lot of weight. Be careful what you lean on when installing parts. The motherboard tray would flex a bit when I was installing my RAM.

Other Thoughts: 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 overcomplicated water cooling setup.

4 out of 5 eggsPremium and Solid

Pros: 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 ball screws, others might not even bother to paint the motherboard tray. Another thing I like about this case is that is manufactured perfectly. I had zero issues lining up my radiators and putting in fans without struggling to drive them in. I've had cases in the past coughnzxtcough that don't quite line up the threaded holes for 140mm fans.

Cons: 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, only when putting the panel back on or taking it off do I notice it. I have to "bend" the case in order to fit it right. Another problem I have with this case is that the case fans that come with it aren't set in tightly and rattle really loudly. Just tighten them up and you're good to go.

Other Thoughts: If you need a big case, just buy it.

4 out of 5 eggsnearly perfect

Pros: good size, features, design

Cons: 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.

5 out of 5 eggsGreat tool for installing video cards & better fans

Pros: Size, flexibility, and design.

Cons: 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 replaced by Noctua black fans (Industrial grade) and long silicon grommets, both just released on May 14' 2014.

5 out of 5 eggsFavorite case

Pros: This case is seriously HUGE. I have 2 SLI 780 ti's with a ASUS rampage IV extreme motherboard. It's very sleek and I love the bottom compartment where I could store my water cooling system (once I get it)

Cons: It's huge, I will explain more below

Other Thoughts: So, this case is seriously huge. I can not stop saying it. It makes my motherboard look small, and everything else in it, even my 2 780 ti's.

I would HIGHLY recommend water cooling from the start with this case. The reason why I recommend it is because the air flow in this case, even with the three fans in the front, and my 110i corsair radiator is very very low. The case temperature still gets a bit warm, again because of the air flow not being very solid.

Again, please PLEASE water cool if you plan to get the case. You will not be disappointed!

3 out of 5 eggsBig, some cheapness

Pros: It's big. It has the space for what you need. The 'basement' is a nice touch. I like the quick release openings. Gotta love lots of hard drive bays. Room for two PSUs. Cable management is always a plus.

Cons: It's BIG. If they're gonna do hot swap, why not all of them? I fully expect to stupidly hit the power button when opening that front panel. The hard drive bays feel cheap and flimsy. The hot swap trays don't always go in right. You have to push.

The front 5.25 bays have supports that come into the space. This blocks multi bay items. This segment is not replaceable or moddable (short of breaking the case and your warranty. This blocked me from installing my 5 in 3 hot swap cage. Corsair support confirmed that nothing can be done (short of serious modding on my end, which would make it un rma-able).

The top vent is hard to get back in without one side slipping over the slot. The basement doors are magnetic, and its easy for them to get knocked loose.

The fans that come with this case (and the H110) are louder than I'd like. I'm spoiled by Noctua, where I have moments of wondering if my computer is on. On this rig, I have no doubt. That said, most people will find them quieter than the cheap stock fans they've encountered before. It was just something that was noticeable to me.

The back expansion slots are thumb screw-ed in. The thumb screws come so tight I needed a screwdriver. It was at this point I became aware that it was really hard to get a screwdriver on them, because the frame blocks it. Had to use pliers to start the turning, then finish by hand.

I'm seriously considering replacing this with a different case based on some of these (can't install my hot swap bays = kind of important to me, flimsy hard drive bays = annoying). Seriously ... that front panel. So easy to mistakenly hit the power button rather than the corner to open the access cover.

And in my own personal opinion:
-It would be nice to have a front door.
-USB3 front is great, but it would be nice to replace some of the USB2 with ESATA or ... something. I don't want 'more' as much as I want 'faster'. I'd say more USB3 but even my rampage IV doesn't have another place to plug that in.
-I really hate those untooled drive trays. It's really unpleasant to put a drive in them. Makes me feel like I'm going to break something (and one of the pins did, indeed, break out). You will also have to pop those off to install your ssd(s). If they really wanted to do a hot swap tray style thing, they should have just used good solid trays from that realm (and then made them all real hot swaps instead of 3/9).

Other Thoughts: I'm mostly annoyed that my hot swap bay doesn't fit. I would have also liked a few more 5.25's so that I could fit another one. Wouldn't be a need if the internal bays were better (hot swappable and more solid).

If I could replace or mod the 5.25 block without breaking the case / voiding the warranty, I'd probably stick with it. I'm still going back and forth on returning it for something else. Annoyingly, the box it came in was so big I immediately broke it down, so I'm not yet sure how I'll return it if I do.

5 out of 5 eggsBig?????

Pros: Big? Huge! The pictures do not do this beast justice! Ample space! Room for two power supplies, removable hard driver bays that can be repositioned, extension cable for your MB (because the case is that big). Stock fans run quiet, several mounting locations for radiators and easy clean dust covers. If you're looking for a case that will provide you with ample room to upgrade, then this is it.

Cons: Heavy! Even without the hardward installed, it is still heavy... But that's not really a con. Most of this beast is metal so you get what you pay for... Quality! Quality just happens to be heavy.

Wouldn't mind a overhaul on appearance, but that is just being picky. Seriously, there is nothing wrong with this case... Ask Chuck Norris!

5 out of 5 eggsHUGE

Pros: H U G E Case... I was able to get all kinds of tools in the case to install water cooling, extra fans and all other components. Plenty of space for HDs, PSUs and mulitple MB sizes.

Cons: Expansion card slots you need to use a right angle screwdriver that is included. That's it though, the ONLY con!
