Corsair has recently announced their new 4000 series cases with a couple of options depending on your needs and design preferences. The 4000 series comes in 3 different models, the standard 4000D with a solid metal front panel, the 4000D airflow which we have here that has triangular cut outs in the front for better air passthrough. And then finally the 4000X with a tempered glass front panel to show off the 3 included SP Pro RGB fans. All three models are available in either black or white color schemes. There is a difference in pricing between the three, with the Airflow, model which we are going to be taking a look at retailing for around $80 or R1700 here in South Africa. 

Overall Design

Corsair stuck to what they know going with a very similar look to their previous Crystal cases like the 220T and 465X. Which we reviewed a while back. The main difference between the 4000D airflow and the other two options is the front panel, which was designed with cooling in mind using large triangular cut outs to help improve airflow and keep the system cooler. But the rest of the case is the same throughout the entire series, you get a large tempered glass side panel and a couple accent pieces in the new bright yellow that Corsair has decided to use on their new line of products. Corsair also went with a pop off front, back and side panel which definitely makes closing the panels a lot easier. However one of the clips did come loose the first time I removed the front panel but it easily slotted back into place and there were no further issues. The case also comes with a super fine mesh dust filter behind the front steel panel that can be removed pretty easily for cleaning.

Front IO

There’s not much to say here, you get power and reset buttons, 1 USB 3.0 type A port, 1 USB 3.1 type-C Port and a headphone and mic combo jack.


Removing the tempered glass side panel you are immediately greeted with a very clean interior that supports up to ATX motherboards, GPUs up to 360mm and air coolers with a maximum height of 170mm. The case does support vertical mounting, which in my opinion always looks great. But keep in mind it does not come with a riser cable and the spacing between the side panel and the GPU is very limited, So cooling might be an issue if you do have a card thicker than 2 slots. The fixed PSU shroud covers up most of your cables and has mounting locations for both of the 2.5” Hard drive bays while still leaving enough space in the front for either a 360mm or 280mm Radiator. As for the top you can fit either 2x 120mm or 2x 140mm fans or equivalent radiator, but clearance will depend on your motherboard and memory choices, as our configuration didn’t leave enough clearance for a 280mm radiator. This is all covered by a magnetic dust filter. There is also a single 120mm fan mount at the rear of the case. The 4000D also comes with an adjustable cable guide that has two possible positions, which really does help keep everything looking neat no matter how thick your cables are.

Included fans

Corsair includes 2 of their new AirGuide non-RGB fans with both 4000D Models, however at the time of writing this review there isn’t much information available other than that they are anti-vortex fans designed to concentrate airflow.


The 4000D airflow excels at one thing and that is airflow, this was the main focus when designing the front panel of this case and I think Corsair did a pretty good job. Compared to the other 2 options and some of their previous cases, which do look gorgeous, but sacrifice on airflow with only side intakes at the front. The 4000D airflow fixes this and is definitely the better choice if you need that extra cooling capacity for your toasty components. And don’t worry Corsair still made it look good with the nice triangular cut outs still let you see all of your RGB goodness.

Rear Chamber

The first thing you’re greeted with are the two 2.5” hard drive caddies mounted against the back of the motherboard as well as a tool less dual 3.5” Hard drive caddy that can be fitted in 2 positions or completely removed depending on your build. The fact that the caddy can be moved further away from the power supply helps hide your excess cables under the power supply shroud, this combined with Corsair’s Rapidroute cable management system made cable management a bit easier. However it was still a problem especially if you want to fill all 6 fan slots with RGB fans and use cable extensions like we did. There is a total of 25mm of clearance between the back of the motherboard tray and the back panel. So managing all those cables, especially the thick 24 pin power cable, can get quite tricky. But this is something that’s a problem with most mid tower cases in general. 


Underneath the case isn’t anything special, you get 4 wide feet that give you enough height for your power supply to get enough air as well as a removable dust filter.

How was building in it?

For the hardware that I used it went pretty smoothly, with no real struggles when installing any of the components other than the fact that we had to go with a smaller AIO than we had originally planned for because of clearance at the top. Cable Management at the back was probably the biggest issue we faced but again we did go all out with 6 RGB fans and some other accessories but I’d say the struggle was definitely worth it in the end.

Closing Thoughts

The 4000D is definitely a great looking case, especially the white version we have. I do like the geometric design Corsair went with on the front panel, the airflow was great and there was enough space to build in. Corsair has made a lot of improvements over my old 460X including the repositionable drive bays and improving the overall build quality. The 4000D is definitely good value for money, especially since it doesn’t come with RGB fans pushing up the price. So if you need a new case and great airflow is something that is important to you then I’d say the Corsair 4000D airflow is definitely something worth considering. Especially in its price class.
