My favorite case
The Corsair RS/4000D frame has been one of the best cases I’ve built in. The airflow is excellent, the layout is clean, and cable management is insanely easy thanks to Corsair’s routing channels and tie-down points. Everything feels sturdy and well-engineered — nothing flimsy or cheaply made.Installing components was straightforward, and the case has plenty of room for larger GPUs, multiple fans, and radiators. My 360mm AIO fit without any issues, and the final build looks super clean thanks to the open interior and simple design.If you want a case that looks premium, runs cool, and makes PC building easier instead of harder, this one is absolutely worth it. Great value and a solid performer.

Amazing case For my first build ever.
As the title says, this was my first PC build ever. That being said, even though I’m a building newbie, I still work in IT and am surrounded by tech, so I knew this case was a no brainer. Fantastic airflow, I mean literally amazing, it lives up to its name. Plenty of space inside for everything you need to do, and cable management was easy, like super easy. Only thing I could have wished for was:A: included a full set of front fans.B: make the top part actually removable, I looked at it and didn’t see a way, maybe I’m dumb, but it didn’t seem like there was a way to take it off, which became kind of a pain when I wanting to plug things in on the top.This is not a dealbreaker however, I just have huge hands that didn’t fit well in that tiny space to plug fans etc in and the cpu power cabling. I admit, this probably could have been done ahead of time and maybe this was just a newbie problem lol.That aside, this case is solid, definitely quality parts when buying from Corsair. I love how simple it is to pop off the front grille and filter, as well as how the front of the case and back side kinda snap off and on, it’s literally strong enough that it can’t accidentally fall off, but not so strong that it’s tough to remove (still use the screws of course for 100% protection of falling off).I never leave reviews on Amazon, but honestly, this case was just the favorite part of my whole build. It’s quality built, it’s got a nice dark black color and sexy style, and if you’re thinking about getting this case, DO IT, you won’t regret it at all I can guarantee that.Lastly I just wanna thank Corsair for making fantastic quality products, and being a name you know you can rely on, which is a big deal in a world where having reliable parts in a pc build is literally the most important thing. I hope everyone loves this case as much as I did.

Corsairs best budget case ever!
This case is by far one of the best cases that you can buy at this price point!The way it’s so modular and every panel is removal makes building in it easy.I was able to place 12 fans inside the case and makes cooling my 9950X3D like a champion! While idling, it stays cool on the lower 40C and while gaming/stress it would stay in the lower 60C. My RTX 5080 didn’t go above more than 43C. The only down fall is you can only place 2 140mm fans on the top or front of the case. Wish you could place 3 on the front but I still love it!I have the Corsair RM1200X shift Power Supply that fit just perfect in it. The great part is it has those tap in corsair screws already on the case to help screw it down. It also has a dust filter right below itFor fans running around 1200rpm, the noise levels were low and had still kept everything cool in the pc.Beautiful case for the price point!

My new favorite case
Great case, easy to work with and work in. I love how just about every part can be disassembled, makes installing the motherboard way easier. I have only used one of the fans it came with due to I bought some RGB fans but so far that one fan has been pretty quite. It is a pretty big case so carrying in as a full build isn’t fun. I have a three fan aio radiator in my and it fits perfectly on the top. So far I have had no issues with cooling I run a three fan aio 3 fans in the front and one in the back, even under load this stays very cool. If your looking for a sleek, easy to build in case I highly recommend this case.

Good quality budget case
It’s a solid, spacious case that made my first build a lot easier. Can’t beat that price either — the RS variant even comes with three fans! Only downside is these fans are a bit noisy at high RPM, although you can tweak the fan curve a bit to make them run slower at the cost of some thermals.The case benefits greatly if you add a rear exhaust fan, which I’d recommend, and can’t understand why they wouldn’t ship it with one although it’s probably to keep the price low.I also like that it’s fairly light weight. Many parts can be unscrewed and taken out, like the motherboard mount and the power supply shield though I didn’t bother to make use of those features. Not much for the cheese grater design of the front panel, but at least it doesn’t interfere with airflow.Well done, Corsair. As the cost of pc building rises you can still fortunately get a quality case for not much.

The Corsair 400d is a fantastic mid-tower case that excels in one crucial area: cooling. Its thoughtfully designed airflow channels and generous ventilation ensure that your components stay cool under even the heaviest workloads.Here’s why I’m impressed:Excellent Airflow:The 400d features ample front, top, and rear intake vents, allowing for optimal airflow throughout the case.Smart Cable Management:The case includes dedicated cable routing channels and tie-downs, making it easy to keep your build clean and tidy, further improving airflow.Supports High-End Components:You can easily fit high-end graphics cards, CPU coolers, and multiple drives within this case.

Bir egzoz, bir ön fan ile geliyor, itx, mATX, ATX ve hatta E-ATX anakartlarla uyumlu, içine devler devi RTX3090 bile sığıyor, yanında da kablolama için cırtcırtlar ve kelepçeler verilmesi, aynı zamanda kasa parçalarının tüm vidalarının tornavida gerektirmemesi gibi hoş detaylar pastaya harika süs oluyor.”Airflow” performansı kıyaslamalarında zirvelerde olmasa da stok halde bile tatmin edici bir soğutması var. Ön panele, ek olarak yüksek performanslı fanlar alırsanız sistemin sıcaklığını dert edeceğinizi zannetmiyorum.Bu kadar övdük hiç eksisi yok mu bu kasanın? Elbette ki var: Örneğin tanıtım resimlerinde gösterilmesine rağmen (yine Corsair’in) RM850 güç kaynağı, HDD yuvası takılıyken yerine sığmıyor. Bunun sebebi kabloların hesaba katılmaması. (Resimlerde de kablo gözükmüyor 😀 ) Yani 850w ve üzeri bir güç kaynağınız varsa ve HDD yuvasını kullanmayı düşünüyorsanız, iki defa düşünün.Bazıları ön paneldeki toz filtresinin fana çarpması problemine sahipmiş ancak ben böyle bir sorun yaşamadım.E-ATX bir anakartı takmak için kablolama yolunu sökmeniz gerekmesi de bir eksi olarak sayılabilir.İndirimli fiyatına ve hatta daha ucuza güç kaynaklı kasalar alınabilir, bu tabi ki alıcının ne tarz bir ürüne baktığıyla ilgili. Fakat hem airflow olup hem de bu kadar şık ve sade duran kasalar piyasada oldukça az. Corsair oldukça sağlam bir marka, üzmez. Ancak burada ne çeşit bir kasa aradığınız kritik öneme sahip.Hem sistemimle uyumlu olsun, hem kurarken beni yormasın, hem sade olsun hem de içi efil efil essin diyorsanız bu kasayı “indirimdeyken” almanızı tavsiye ederim. Keza normal fiyatı olan 1K küsurlara deyeceğini zannetmiyorum.

エアフローがしっかりしていて良く冷えます。自由に組めるので大体の人はこのケースで十分だと思います。

Wow, the easiest box I have ever built a PC in, everything is modular and removeable if you want. The amount of air the front 3 fans draw in is amazing (I got this because of air flow, it gets hot here in Perth!).

What an excellent case… I’ve built in a fair number of cases now and this one has the best construction I’ve seen.Keep in mind, this is a smaller case. If you’re not prepared for that, I could see it being irritating. But it fit three 120mm case fans up front (Noctua or nothing!) and a 280mm cooler up top. If you want to use a 360mm cooler on the top, it isn’t going to fit, but the 280 is a really nice fit.Other than that it looks really sharp, has a ton of thoughtful design features — like sensible channels for you to run your cables through — and a great build quality. I can’t recommend it enough. My next computer might be in the same case.
