Product Showcase - Interior

Let's have a look at the interior. You will notice that the design is a bit different. You can install SSD/HDDs on the backside and optionally two SSD at the PSU cover. There is plenty of reach and space to access the motherboard and you can fit pretty big components. The 4000D supports graphic cards up to 360 mm in length and, for the CPU cooler, up to 170 mm (CPU die surface to side panel). So that is plenty for even an RTX 3090, but CPU cooler wise a bit short. We'd advise an LCS here.

The top side dust filter is pretty much a rubber meshed mat with magnetic strips in it. Works superbly really.

At the front side, you can rip out the bezel (metal) and then rip out that dust filter to clean her up or to access the single fan located at the front side. You can see Corsair placed it higher, no pushing in the air directly at the GPU. At the rear we'll spot the second included 120mm AirGuide fan. A roomy heart fits up to 6x 120mm or 4x 140mm cooling fans, along with various radiators including a 360mm in front and 280mm in the roof (dependent on RAM height).

 
Airflow is pretty terrific thanks to the strong intake fans and massive airflow gaps in-between the glass panels. Cable routing issues are simply non-existent At the top side you could mount a  280mm or 240mm radiator, however, you should be careful with DRAM height. Corsair recommends that LPX DIMMs cooler there (thus any sort of low-profile memory). But yeah, choose wisely or simply mount the LCS at the front.

   
Located just under the rear fan we spot 7 PCI card slots and 2 vertically mounted ones for a graphics card (riser cable not included). All the way below of course is the PSU compartment.
