    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.

    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.

    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!

    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.

    This case is priced extremely well for what you get it has enough room for 2 240mm AIOs and all the RGB fans I could possibly need not to mention my 3090ti clears the double fan rad setup with plenty of clearance for air flow. However putting a full size 3090ti in a vertical mount the air flow isn't as good as my AIO Strix LC only has a couple MM of Clearence with the tempered glass

    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.

    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.

    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

    Absolutely love this case. I bought a pre-built Asus that was getting gaming Temps at 85-90+ Celsius. Swapped PC cases and added a liquid cooler and now my gaming Temps are 55-60+ Celsius. I would definitely buy again. 100% recommended.

    So like the title implies the case looks very nice. But it doea have some things im not super thrilled about. First thing is corsair please include the rear fan with these cases because without it it has terrible flow. I run a 5600x asus x570 and a rtx 3080 currently. Anyway so i had this thing air cooled at first and twmps were up mid 90s twrrible so i added a rear fan got them down to mid 80s took the side panel off low 70s . This is all under full game load. And those are cpu temps. Anyway ended up putting a liquid cooler in the case h115i lets say its probably to thick for this case on top but thata where it is now just touching the ram. Not my favorite but it works the problem is the 140 fans on h115 are too thick. The h110 fits perfectly and i would go.thst direction n3ct build. But with all that in there it runs 72 to 76 under full load 1440p or 4k . The last issue is if you want to vertical mount the card which looks cool its too close to the glass to be actually usefull. It overheats the graphulics card and im talking 92 so thats useless with a 3080 or probably any large card i would assume. Hopefully that answers many questions if i could rate it a 3.5 i think thats a accurate number.

      Posted .

      Hi,

      Thank you for your feedback. I suggest making sure the top fans are also oriented to exhaust air out. When installing a 280mm radiator in our 4000 Series cases, we recommend users to use low profile RAM. A 240mm radiator would not require low profile RAM. If you have any questions, please feel free to reach out - we'd be happy to assist: help.corsair.com

    I recently ordered many computer parts from different sources and when I was finally got home from college started putting them all together when I noticed that the case I ordered from Amazon came badly damaged so I refunded it but I needed a case within the next two days otherwise I wouldn't be able to finish building the computer before going back to college so I bought this one from best buy to replace the broken iCue 5000x rgb and i was worried that this case would not fit all of my components but it fit perfectly and was an easy build experience! Absolutely love this case! For those wondering what I fit into the case: Asus ROG z-690-A motherboard which is full size atx motherboard (but the case has holes for smaller boards so there is no need to worry about that) an rtx 3080, a 360 mm AIO water cooler (corsair) you will need to front mount any 360mm water cooler as the top of the case does not have space for more than a 240mm aio so that is something to be aware of. I have a 1000 watt power supply this does make it so that i cannot have any hdd drives since The cables from the power supply take up that extra space but if you have a smaller power supply you can fit the hdd mount just fine. it also has two two ssd mounts in the back of the case behind the cable management cover that are very useful for more storage that I will definitely take advantage of in the future!
