It has a cool little stem to support your GPU in case you have one of those long and bulky ones whose weight could be concerning, especially when mounted the traditional horizontal way. The air intake fans are very nice and effective; super silent. Back side has a great cable management setup which is very easy to work with. And the PSU compartment has good space for you to work with, even with the PSU already installed. All panels are extremely easy to remove and I truly appreciate how each panel screw stays with each panel so that you don't have to pile up any screws when removing the panels. I honestly have zero regrets nor complaints for this specific case after a month pr so of use. Truly worth every penny. By the way, the PC in the picture that is sitting on top of the case is an Optiplex 390 office PC, which is my old one for comparison.

Fantastic case! This one is super easy to build in, lots of space for fans, and large components, modular design, and the build quality is awesome! I had the original 4000D and it was subpar, but this one is great! I’m coming from the Lian Li O11 Air Mini, which is also an amazing case! I just wanted something different. I think my build would look better with a 360mm AIO, or just switch to air cooled, but im happy regardless.

Great Computer Case! The Corsair 4000D Airflow very well-designed mid-tower case (rather large compared to my old mid-tower) with excellent airflow. I was able to mount a radiator on the side but some might not fit due to thickness. Building inside it is easy, with good cable management (yes really) and sturdy metal construction. Front I/O is what you would expect. One thing to consider is the size... she takes up a good bit of desk. Overall, worth the money! *in the picture, the right case is the 4000D*
