Quality is there!
Air flow is good, and I get and maintain great temps, even when stressing/Gaming for long sessions. The PSU Bay Area can be tight if you plan to use the hdd cage and if the PSU is long, or an issue with my Seasonic focus 1000w.
The case comes with RGB fans installed (4) and has good space for all components, usb -c, with usb -a headphone/microphone port. Tempered glass to the front and side, remember it’s glass and they will shatter.
The vertical mount for the GPU is only if it’s like maybe a 2 slot card, or water cooled, anything larger (any good ones) will be too close to the glass and won’t get ventilation, the ability to cable manage is there and can do some good cable management.
Top has room for 240/280 radiator Aio. Can mount 120mm/140mm.
Overall the case is solid for what it’s meant to do.

I’m running a power hungry i7 980X and 3x 980Ti in SLI. The glass panel looks really good and the case feels solid. I added a few fans to help with the airflow. I like the vertical gpu option as well. I got it on sale and at the sale price it’s easily one of the best cases you can buy.

Solid case, great size. It’s a mid tower atx with a slightly longer dimension. *Fits my EVGA 3080ti with extra room.
*RGB FANS ALONE WORTH The Price!
*Great glass and very nicely tinted.
*EASY TO INSTALL, fit my top mounted AIO 240mm perfectly. Fans facing outward to the top and all 3 front fans facing in.

Decent case, decent airflow, iCue bad

Decent case, I enjoyed that it came with the three 8-LED fans in the front plus a node inside the case to connect those fans to. Easy to build in for the most part, and the design of the case looks very nice.
Their glass side-panel mounting solution could be better, the side panel feels pretty much suctioned to the case which caused me to shatter my first one (super fun) and always gives me resistance so it can be dreadful to take off for getting inside the PC, which is obviously necessary.
My real gripe lies on the other side, towards the back of the MOBO. I'm running the 850W PSU from Corsair, and the cables are so thick (mainly the 24-pin) that even pressed all the way against the back of my case, it still causes the outer panel to bend, and (not trying to flex) my cable management inside the case is pretty much flawless. Rather ironic I would say, that I pair a corsair PSU with a Corsair Case, and their cables won't even fit in the back panel properly, which makes adding cable extensions or extra fan headers to this case pretty much a nightmare.
Also, I know this is a common thing for RGB fans, but the double wires for one fan (one for RGB and one for actual fan control) is a little ridiculous. If you're mix-and-matching fans from Corsair, like me (one LL fan, and five 8-LEDs) you (might) have to get an extra node/header to control them since they use one fan to tell the others what to do, or else the RGB won't work properly on one series of fans (I could've planned for this better, but really).
You might know this, but iCue can be pretty awful. Most recently, I was having an issue where my fans connected through a Commander Pro would go on and off every 5 seconds and a USB-disconnect sound would sound every time the fans would turn on and off, and my fans would go full-throttle when it happened. I fixed it by disabling some USB setting, but most of the forums I visited said it's an issue with other programs interfering with RGB control, so take that as you will.
THERMALS AND NOISE PERFORMANCE: I'm running a Gigabyte 2080 super and an i7-9700K (stock OC, same voltage) with a h100i Elite Cappelix 240mm AIO mounted at the top of the case (there's an option for 280mm but my RAM, corsair vengeance RGB, barely had clearance with the 240). My CPU never goes above 65 degrees and same with my GPU, so I can't complain about that.
Under load, I would say the noise level is alright, it can be quite loud but the tone of the noise isn't unpleasant. Compared to something like the jet engine of a PS4, this is way better, it just sounds like a really big fan blowing wind without any mechanical noises or whirring, so I would say a clean sound.
PROS:
- RGB looks nice especially with smoked panels, overall very sleek-looking case
- Decent-good airflow and performance.
- Relatively easy to build in.
CONS:
- Area behind MOBO for cable management is too small for Corsair PSU cables, bends my side-panel even without stacking wires + good cable management.
- iCue is not good
- Glass side-panel mounting needs improvement, can be annoying
- If running with Corsair fans, LOTS OF WIRES
In short: I love the way it looks and it performs well, but for individuals who are less experienced, it can be quite tedious to deal with Corsair's software if pairing with other Corsair peripherals. If you're not looking to build with Corsair fans, go find another case 100%! Be wary of pairing with a PSU that uses thick cables.

Absolutely perfect case! I7-12700k CPU, ROG Z690-E Gaming Mobo, GeForce RTX 3060ti GPU, 32gb Corsair Vengeance RGB, Corsair iCUE H100i Elite AIO. Everything looks smooth with all the RGB lights and boy does this case breathe!

Case is amazing, has a nice tint to the glass panels, very well ventilated and over all great so that your pc has a good way to breathe and your inside isn’t dying. Although the case is nice, I do have to say the the lighting it displays on the photo don’t really work, at least mine don’t. Not sure if this has to do with the fans or just me but from the videos I’ve seen, they don’t always work but what’s important to me is that the fans work and they do so not much complaining here. If you want a well ventilated system this is definitely it, and if you wish for both then you’ll have to buy a set of different fans on your own.

Corsair makes some solid cases and others have more airflow than this. However, I haven't had any issues with this case. I wanted a glass front and something that came with fans. These aren't Corsair's top end fans, but they work. I added another LL120 fan on the rear exhaust so I could use the controller it comes with. Corsair does not let you mix and match fans with their controller.
You technically can, but controlling the RGB doesn't work out. I paired this case with an additional LL120 fan and their H100i elite LCD AiO. I paid more for their LCD AiO, but it looks nice, and I wanted to use one program (iCUE) for managing all RGB.
I have iCUE set all fans to quiet operation. My system consists of a Ryzen 7 5800X CPU and RTX 4070Ti graphics card. I put five temperature probes throughout my tower so I could measure the air temperature coming into the case (top and bottom), what's coming directly into the graphics card under it (above the power supply shield), what's leaving the back exhaust, and what's being pushed through the AiO out the top.
Internal case temperatures while gaming never go above 40°C while my CPU sits at 65°C. My graphics card gets warmer, around 80°C, but it's a power hungry 4070Ti and it's still well below any levels of concern.
Overall, I'm pleased with this case and the performance it provides. I could probably get some cooler temperatures with one of their airflow cases, but I prefer the way this one looks. The front glass is a nice touch and the glass around the system is easy to see through. I do wish it was 1-2" taller for easier cable management, especially since I have 6 fans with RBG, the LCD AiO, and 4 of Corsair's LED strips all paired to four Corsair controller boxes each requiring SATA power. Things would be an absolute mess if I didn't have a modular power supply.
There are options for cable management in the back, and Corsair gives you 5-6 Velcro cable straps and a dozen or so small zip ties. There are multiple hooks and loops for cable management, it still becomes a mess when there's this much lighting in it.
Either way, there's plenty of space for 40-series and 7000-series graphics card and adequate cooling.

Quality build, reasonable price. Room for a mid-tower with space for a 240mm and 320mm radiator. Good cable management.
Glass front panel gives a high-end look, but if you need airflow go for the 4000D as the glass panel restricts airflow. It's still decent, however, and Corsair's ecosystem for RGB is second to none. Plan on spending a little extra and getting a Commander Pro to make life much easier.

WORST REVIEW EVER

I love this case! Great airflow! The tint hides all the stuff you don’t want to see. RGB SP fans. It also can accommodate the biggest graphics card that’s made. RGB SP fans. Did I mention fans? Not a bad deal with the fans! RGB fans work flawlessly with Icue. I paired that up with some RGB Corsair Vengence, and Corsair Lux 240mm AIO. It looks like a pawn shop in Vegas. I love it! Here’s the bad. The front panel shattered and not just a little bit. It was a huge mess to clean up. My wife was politely, very upset. I was very gentle in pulling too. I suggest that you pull from the top and bottom of the panel. I pulled from the middle and I was left with nothing in my hands. Crazy!! I highly recommend this case. I used this for my wife’s build and I went with the 4000d airflow, after having terrible cooling issues stuffing everything into a 280x. Merry Christmas everyone! I’ll be dropping 20 bombs in the Warzone @ 143fps in 1440p thanks to BB!

Huge great case. I used to have a small corsair case that couldnt fit my water cooler up top but this one solved the issue, and it provides alot of room inside. My only complaint is that the tint is alittle on the darker side so you wont see the rgb too much lol

The Corsair iCUE 4000X RGB case is the culmination of years of development, and it shows clearly in the iCUE 4000X.
The case is the best engineered and implemented case I have used for my builds; it dots all the I’s and crosses all the T’s.
Not one of the cases I have used over decades was so completely thought out built. Have cases costing far more than the iCUE 4000X that do not come close to the excellence of this build.
Notes:
- RGB controller is intuitive to use, works great with the ICUE software.
- Side panels and the front panel are easily removeable.
- Cable management channels are superb.
- Magnetic dust filters are easily accessible. Great stuff
Do not recall a case that something was lacking or just not right, not the 4000x, they got it right.
If you are looking for a case that delivers on capacity, ease of installation, airflow cooling, upgradable, solid build and delivers at a fraction of the cost of many cases give the iCUE 4000X a look. It is truly a Winner.

Best mid tower case for air cooling. Im runnin high quality graphics on my 3080 rtx for hours and have yet to reach max temp on gpu or cpu, i added 3 more corsairs rgb elite for proper air flow. The design is sleek and the cable management is amazing thanks to the convenient channel corsairs has incorporated. Overall completely satisfied with my purchase and would definitely build another PC with this case.

After reading many reviews, I decided on the Corsair 4000x. Corsair is well known for quality products. The factory installed Static Pressure (SP)120 RGB and lightnode worked flawlessly with my Asus TUF motherboard. The tinted tempered glass panels allow me to show off my build. The backsude if the motherboard mount channel allows for a very clean layout. Nobody ever shows the backside because nobody ever sees, but here is one.
