The Corsair iCUE 4000D RGB Airflow is a mid-tower ATX PC case engineered for exceptional cooling and stunning RGB right out of the box. This black variant includes three AF120 RGB Elite PWM fans with AirGuide technology, an iCUE Lighting Node PRO controller, and the RapidRoute cable management system – everything you need for a tidy, high-performance build.
Whether you're a first-time builder or upgrading your rig, the 4000D RGB Airflow offers a perfect balance of airflow, RGB customization, and buildability. Its high-airflow steel front panel and spacious interior support up to 8x 120mm or 4x 140mm fans, along with radiators up to 360mm in front and 280mm in the roof (dependent on RAM height). This case keeps your components cool even under heavy loads.
The included AF120 RGB Elite fans spin up to 2,100 RPM and deliver 65.57 CFM of airflow, while AirGuide technology focuses air for better static pressure. With the iCUE Lighting Node PRO, you can control RGB on up to six fans, syncing lighting with your setup. The case also accommodates a 360mm GPU and has two additional 120mm fan mounts on the PSU shroud to direct airflow straight to your graphics card.
Routing cables is a breeze with the RapidRoute system: a dedicated channel, tie-down points, and a hinged cover keep your build looking clean. Modern front-panel I/O includes a USB 3.2 Gen 2 Type-C port, a USB 3.2 Gen 1 Type-A port, and a combo audio/mic jack, putting your connections within easy reach.
For a successful build, start with the PSU and cable routing, using the RapidRoute channel to keep cables tidy. Install the included fans as front intake for optimal airflow, and consider adding two additional fans on the PSU shroud to cool your GPU. The case supports ATX, micro-ATX, and mini-ITX motherboards, so you have plenty of flexibility.

Looks awesome.
The case is well-built and the airflow is fantastic. The RGB fans are vibrant and easy to control with iCUE. Cable management is a breeze. Highly recommend.
Good case, but the cable management channel is a bit narrow. The RGB is great, and the fans are quiet. Overall satisfied.
I built my first PC in this case. The RapidRoute cable management makes it super clean. The included fans are excellent and the RGB looks stunning. Plenty of room for a large GPU. Couldn't be happier.
The case looks good, but the included iCUE Lighting Node Pro doesn't have enough ports for all three fans if you also want to control the RGB strips. I had to buy a separate fan hub. Also, the side panel is glass but easy to smudge.
The 4000D is a dream to work with. The cable routing is intuitive, and the straps are a nice touch. The fans are quiet and the RGB is customizable. Thermals are great with high airflow. The black finish is sleek. Worth every penny.
The case is well-designed, but the stock fans are a bit loud at full speed. I had to set a custom fan curve to quiet them down. Other than that, excellent build quality and looks great.
This case is perfect for showcasing your build. The three included fans plus the Lighting Node PRO give a stunning RGB effect. The airflow is excellent, keeping my CPU cool even under load. Cable management is genius. Love it!
The case is great, but I had to add an extra fan for better airflow because my system runs hot. The RGB is nice, and the build quality is solid. Just wish it had a USB-C front panel connector.
I was deciding between this and a more expensive case. This one won. The build quality is top-notch, the RGB is vivid, and the cable management is the best I've seen in years. The included fans are high quality and move lots of air. Highly recommend.
The case itself is fantastic – looks great, good airflow, easy to build in. But the manual for the iCUE Lighting Node PRO was confusing; I had to watch a YouTube video to figure it out. Still, five stars for the case itself.
This case has everything I wanted: plenty of room, excellent airflow, and beautiful RGB. The cable management system is thoughtful, with straps and channels that make it look clean. The tempered glass panel shows off the RGB. It's a joy to use.
