Customer Ratings & Reviews

The Corsair - 4000D is one of the best mid sized ATX cases that I have used. Pros - Great air flow, high quality, looks good, and perfect size. Cons - None! If you're looking for a great mid tower for around $100, you can't beat it. It fit my 3090 surprisingly well. I would recommend and probably will end up getting another one soon.

So I built a very basic PC from scratch, my old one was too small for my new ATX motherboard i had. I just wanted to play starfield. Super easy settup. Depending on what power supply you get, cable management may be a bit messy but i am really happy with my purchase. I have no extra fans currently, without RGB fans it is a simple, beautiful case, not flashy. With RGB Fans I am sure it will look even more phenomenal. There is an air vent on top that helps with ventilation, with a magnetic mesh style cover that goes on top to keep dust out for when you dont need to let heat out. For the price you cannot miss on this. Seriously was well worth it. Definetely planning on upgrading in the future and this case will be the constant.

Nice looking case with good airflow and room in it

Probably the best case out there on the market. The magnetic dust filters are amazing at keeping the dust out of my pc. On top of the sleek minimalistic design, tinted glass panel, and great at keeping your thermals low this case is a must for the price. My only gripe is that it only has 1 USB port and 1 USB C port on the front but other than that it’s solid case.

Oh my goodness, the little things about this case all make it so worth every penny. Great internal layout, amazing cable management possibilities, excellent air flow, room for a 240 or a 280 rad up top, and up to a 360 in the front. This was so nice to build in compared to other cases I've built in in the past 15 years.

It’s super easy to work with, has good airflow, and cable management is a breeze. Plus, it’s simple and affordable—definitely worth it!

Amazing case for the price! Has awesome airflow. Great aesthetics and superb cable management options. This case with my original fan setup dropped my temps over 10c. Used to sit at roughly 78-80c in VR gaming with a 3060ti and i9 9900k at 5ghz. Now at full load it maxes out at 69-71c. Lots of options for what ever you may need.

I really like the minimalist all black design, the tinted glass side panel is also really cool. The inclusion of velcro straps for cable management was a nice extra as well.

It's a metal box with glass sides. I don't have any fancy colors in my system, so don't much care about the glass, but it holds my ATX board just fine, and comes with two big case fans. Pretty roomy inside, and seems well built. More or less the same attributes you'd want when car shopping. This is much cheaper than most cars, thankfully.

Solid case, good airflow, excellent routing options for cable management. Solid case and pretty cheap at that.

Great case for my massive computer I'm very pleased with it

Amazing case, plenty of room for cable management and permits excellent airflow

This case is huge! i love how much access you have for cable management. The airflow on it is insane . i dropped temps on my PC

This case is a very nice case for the price. Roomy and sleek, I’ve done two different builds with this case it was recommended to me by a friend who has also done a few builds with it. The glass panel is solid and the vents are all easily removable to keep everything nice and clean. The only reason why I’m not giving five stars - Best Buy didn’t have any color variety, I was hoping to get this Build done in white and found this case in many other stores in both white or black, but only black at Best Buy. I had rewards money that was going to expire so I settled for the black.

Absolutely great case. Solid build quality and tons of room for cables. Great airflow and nice looking tinted glass. An overall eye-pleaser. The only thing to note is that a 360mm AIO can’t be mounted with the pipes on the bottom because of the PSU should. I would still want this case over a similar one that allows the upside down AIO though.

Excellent case so far, great airflow and plenty of room for expansion!

Superb for its price. It's an airflow-focused mid-tower case with a small enough footprint for my desk and it was exactly what I needed for my build. It was very easy to build in and every component is of high quality and feels sturdy. The removable filters on top and in front make cleaning very easy and prevents dust build-up; I've owned this for several months and the interior is still mostly dust-free with just cleaning the filters. CPU and GPU temps are low thanks to the large intake areas; however, I would recommend getting at least one more front intake fan to optimize internal airflow. The side panel is a tinted tempered glass; I'm not a big fan of RGB, but the lights are still visible, just without a ton of bloom or glare if that is your liking as well. My only gripes would be that I wished the top panel featured one more USB-A connection and that the hard drive cage on the bottom was easier to move around for cable management, but those are really just nitpicks for a great case. I believe the newer 5000D has optimized the design ever more, but the 4000D is still a great contender for the best airflow case in recent years.

I like this case so far there’s room for everything I need and then some. The mesh screens are a nice addition as well. Also the cable management works well.

Awesome pc case! Will be my first build that I’ll be doing. I’m super excited it’s super spacious and sleek on the inside. You can do literally everything with this case!

Just bought this case recently and I really like it's design. The airflow through this case is pretty nuts. My only recommendation is to buy a set of fans if you're going to get this case cause it only includes two in the case.
