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

Cheaply Made / Not worth $350


This fits my 480 and 360 mm rads and 2 reservoirs and that is the only reason I am keeping it.

Huge ; Good expansion space ; Nice Side window ; Great water cooling supports up to a 480 on top which I can attest to fitting well

Magnetic bottom doors wont shut unless jammed up under door lip on both sides ; The I/O port broke off on me on first unclipping ; No instructions on how to attach bottom radiator mount

Liquid cooling dream case


Get a sturdy desk to put this case on it is very heavy.

I got this case for a liquid cooling build I'm doing and honestly... you can go totally nuts with this case the size is a SUPER tower. It carries support for up to 5 radiators that can be used simultaneously. I Will only be using 3 in this build, plus...

None so far

The premier enthusiast tower case


Overall, an excellent case that looks great and is probably one of the most functional on the market... minus the ability to secure large video cards to the chassis. I wouldn't really consider taking it to a LAN party due to it's weight and dimensions...

I won't mirror what others have stated for the pros, but there are many. This case is probably best suited for liquid cooling, although air cooling is entirely possible - mainly due to the fact that it can house - without modification - 10 x 120mm...

This is the part that gets me. If you are considering this case then you are most likely in a different class than your average PC builder. You would expect to be able to put massive, bleeding edge VGA cards in this case AND be able to secure them to...

Maximus 5 formula G-Skill 16gb 2133 3770k @4.9 (Average temps on all 4 cores are 18 - 24c idle , 40 - 45c on load! ) Alphacool Nexxos Monsta 420 Aplhacool Nexxos Monsta 480 Ocz Vertex 4 512gb 2x Evga Gtx 770 SC Corsair 1200i

Everything I could have ever asked for in a case has been answered by corsair ; I was able to fit two Giant Alphacool Monta rads in this case ...One 420 on the top (80mm thick!!), and a 480 on the bottom (80mm thick also) and still have plenty of room

Best Enthusiast Case


Some might argue that the price is a bit steep, but I have no regrets with my purchase. It was nice not having the case being a limiting factor for the things I wanted to do with my build. I imagine the case will last for a few builds, so the $ evens...

Easy to create an extremely clean build with a multitude of fans, custom cooling, I/O, etc. due to the space and cable management options. You will find that a lot of thought was put into engineering the case as you're working on it. The most pleasant...

Limited availability during initial release, limited documentation on the case (though I didn't need it)
