The last case I'll ever buy. 7/8/2019 2:50:35 PM

Pros: Massive size.
Easy to have clean cable management.
Lots of air-flow options, mine personally has 12 fans, and a liquid cooler.
Easy to access, and put pieces in.
Literally massive.
So big it makes my 34" monitor: AW3418DW look small.
Gorgeous brushed aluminum, makes even the stickiest of toddler finger-prints just wipe right off.
Because it's so tall(27 Inches) when it's on my desk, I don't have to worry about my 4 year old pressing buttons, and messing anything up. It's simply too large for her to reach.
Massive open poly carbonate window, so you can see your computers glory.(Also keep an eye on LED readouts, and error codes)
Subtle, yet loud. In your face, but shy. Distinguished class, insurmountable elegance, quintessential grace, joie de vivre.

Cons: The side panels can be a little bit of a hassle to get on or off.
The Top Panel it frustrating at first, you'll warm up to her eccentricities.

Overall Review: This will be the last case I ever buy. That's not just some hyperbole, I literally will never need another case, the 900D is the perfect case.

Easy to work with 12/10/2018 8:21:49 PM

Pros: I got this case because I'm one of those old timers who still runs cards in SLI, I like loud fans, and I have a watercooling system with a 60mm thick 360mm radiator (HWL Black Ice GTX 360) with soft tubing. Right now I'm only cooling the CPU but I'm stepping up to a monoblock. It's easy to work with, I don't have to mod anything to make it work, and even with 2x GTX 1080ti cards in SLI I still have enough room for everything else.

Right now I have a total of 15x 120mm fans in the system and I'm proud that I do. The only fans that are going to waste are the ones I Installed at the bottom of the case. That area is really ideal for mounting a 480mm radiator if you need to.

If I wanted to throw another 240mm or 280mm radiator in the system then I would have no trouble doing so.

The main selling point for me was I have a friend who's had the 900d since 2009 and he likes it, and I was able to reuse my 5.25" pump/res combo in this system. With newer cases I would have had to change over to a cylinder type pump/res combo. I also have a DVD/RW drive that still gets used sometimes so it was nice to put that into the system.

Cons: Cable management options and routing could be better.

At the top of the case I have my 60mm this radiator combined with 2x 25mm thickness of fans, 6 in total. 110mm is pushing it and I have very little to no room for cable management.

Very, very heavy with all the hardware installed. If someone tries to steal the system, they had better be buff. At least I can deadlift 300lbs.

Overall Review: No problems for a system with:
Core i9-7940x (4.6ghz Binned by SL) I bought it on my own but had them delid.
Rampage VI Apex
32gb DDR4-3600
(Formerly 4930k, RIVE board, and 32gb DDR3-2400)
2x EVGA SC2 GTX 1080ti SLI
EVGA 1600w T2
2x 850 pro 512gb
970 Pro 512gb
8gb Seagate Barracuda Pro

(Used to have 4x Samsung F3 1tb drives for Raid 0)

Not up to Corsair quality standards 6/27/2018 10:15:00 PM

Pros: It’s massive!

Cons: Virtually everything about this case is cheap, flimsy, “plasticky”, and poorly built. The hinges WILL break, the removable panel ejection buttons don’t work! Which raises the question! How am I supposed to remove the side panels to access the interior of the case?

Overall Review: I buy Corsair components almost exclusively for my computer builds, and this was a huge let down. Corsair could have done much better in the quality department.

Pros: Big
Fits a lot of components

Cons: The magnetic flaps in the bottom are poorly made and if the case even moves slightly they fall open

Dang big case, solid quality and room to grow. 6/18/2018 8:43:28 PM

Pros: Space.. lots of it

Cons: 5.25 bays? With a case this big it'd be nice if the expansion bays were somehow as optional as the internal drive bays. With a bayres/pump, fan controller and SD card reader/SSD hot swap installed I ran shot on space for my DVD, cup holder and cigar lighter. Had to lay my second fan controller inside the case.

Overall Review: This is a well built case.. would not hesitate to recommend.

Best case I've ever owned 4/16/2018 8:57:11 AM

Pros: - Fantastic cabling options. Makes for a clean setup
- Fans are silent
- Everything but the kitchen sink

Cons: - Size. This is a pro if you need it, but just be aware that this thing is the size of a small country.

Overall Review: Won't buy another brand case ever again. Corsair really goes above and beyond, and the quality is tangible.

Great Case, Love it! 2/2/2018 11:57:09 AM

Pros: Very large, and seemingly very durable. Should last you a long time.

It has plenty of room to build and expand in. Plus this case was purpose made for water cooling.

Cons: Quite heavy, coming in at around 50 lbs. This may be a bit too much for a desk or a table to handle, so check its rating! One problem that I almost had was that the case itself is 10 inches wide, 25 inches long, and 26 inches high. This was going to be a bit to long for the desk that i was getting to handle. Instead i had to buy a bigger desk to fit this massive beast.

Also for some reason the side doors are sticking a bit, but i think that over time that will go away.

Overall Review: I would definitely recommend this case to computer and gaming enthusiasts, but it is not for a beginner computer builder. While it is quite easy to work in, the price and sheer size it just too much for a first timer. If you are interested in building for the first time, I would personally recommend the Corsair 750D

Monster! 1/15/2018 1:52:14 PM

Pros: Internal space!
Plenty of grommets with rubber gaskets

Cons: GPU thumb screw location!! Seriously who thought that was a good idea? If you get a angled screw driver you are fine but defeats the purpose the "thumb screw"
No option for casters (it is heavy as expected)
