Customer Ratings & Reviews

The CORSAIR 4000D RS is hands-down one of the best mid-tower cases I’ve worked with. The minimalist design looks clean and modern, and the build quality feels premium right out of the box. There’s plenty of space for airflow, cable management, and future upgrades. I appreciated the roomy interior and smart layout—it made my build process super smooth. The tempered glass side panel is a nice touch too, giving a great view of your components without being flashy. If you want a functional, great-looking case that makes building easy, this one’s a winner.

Nice amount of room to fit and cool all of the components. I like the modularity and easy removal of each side to access compartments. Definitely read the instruction manual on Corsair’s website to get the full scope of the features. This case is great for 1st time builders. The infinity rail system is a neat idea but the case doesn’t come with extra spare runners for the rails. Those must be bought separately. Taking a star off because the cheap rubber handle for the top face broke on the 1st pull. Yes the thumb screws were undone and this was not a fast/hard pull. If you want to take the top panel off the pull from the sides of the panel towards the rubber handle but don’t use it the handle itself.

Actually an awesome case. Shockingly easy to modify and fill with fans if youre running a particularly toasty setup. Amazing value, you cant ask for more in a case.

great case to build from. Best buy matched an Amazon price so that I could pick up same day in store!!

I moved down from the 5000D to this case and it is liter and easier to put together. Also it looks alot nicer. No problems putting in the any of the newer and bigger componets.

I was actually really surprised with how well put together this case is. It's super easy to build in especially compaired to a lot of the cheaper cases I've worked with for my friends PCs. HOWEVER, at higher RPM the fans that came with the case have an unacceptable coil whine. As is commen with cases that come with fans. I had to turn them down. It bothers me that cases come with subpar fans and I want that to stop.

Good versatile case, Good quality and easy to build in. Filters are easy to remove and clean. A lot of cases don't have filters now, Its a must if your have furry pets This model comes with 3 fans that are not RGB. They do have a model that comes with RGB fans but not everybody wants RGB in their builds.

Good case for what it’s worth I like the modular design

Super roomy with lots of airflow and options. Super nice and high quality.

Quality of case is amazing. Budget friedly and love the design on it and the amount of airflowed allowed into it

Perfect fit for a big motherboard and a water cooler

Fits an ATX motherboard perfectly, this is not an E ATX case, but easy to work on and build in.

Gives you tons of freedom for fan choice and placement. Very builder friendly for newcomers and for those looking for more customization.

This is the perfect case to start your build, so much room for growth and future mods even has its own kick stand for your thicc boi gpu's.

I like the accessibility of this case. very easy to get your build in and cord managed quick.

Awesome unit, all the space I needed for my build and a great look. Plenty of airflow

Good case. Not hard to work with. Like the captive screws so you don't loose them. It's big, so I don't have it on my desk. It'll get heavy as you put components in it.

Great PC case. Easy to build in and use with high quality features. Great value for money. Purchase on sale which was even better.

Great airflow and easy cable management. Easy assembly as most of the panels can be remove for easy installation. The 3 included fans were a nice bonus and theyre quiet.

The price ratio of what you pay and what you get is really great. I love the case. It was easy to build in. Also, I love how it has magnetic dust filter for easy clean.
