A Closer Look - Inside

To access the interior, simply remove the thumb screws and pull the panels off the case. Corsair has included push pins on each side, so the panel holds in place nicely even with the screws detached. Overall, this implementation is excellent and feels solid. On the interior, things look quite traditional for a modern chassis with a metal shroud on the bottom. You may install your 2.5" HDD plates here to show off your SSD, but those are installed behind the motherboard tray by default. I am not sure if Corsair sells these separately for those who want to add more storage. There are also two fairly large cable-routing openings in the shroud, which could have been cut much smaller to keep things as clean as possible.


The other side of the case does offer a few elements that stand out. For one, the screw holding each of the two 2.5" trays in place comes with a yellow accent. There is also a cable channel with three of the wide Velcro Strip built right in, so you should be able to keep things pretty clean for the most part.


Underneath the shroud, the PSU bay is standard fare with its foam bits for the PSU to rest upon. Above that are the expansion slots with their individual thumb screw, each, which is nice to see in a case of this price point. The retail-quality 120 mm exhaust fan in the very top may be adjusted in height to align with your air cooler.


Looking at the front, you will find a cage with two 3.5" trays which may also hold 2.5" drives. This brings the total storage placement possibilities to four. The area above that is meant for intake cooling or your radiator setup. Corsair also includes a cable-routing cover which comes with a little branding and a yellow square just for kicks. For ATX boards, you may leave it in place, but it needs to be moved towards the front of the chassis by about an inch with an E-ATX motherboard.


The opening in the ceiling for air or liquid cooling is well positioned, as it is as far removed from the motherboard as possible, which avoids any component collisions during assembly. Corsair also uses a solid PCB for their I/O, which speaks to the quality of the chassis as well.


All the cables within the Corsair 4000D Airflow are black and mostly what you would expect. The USB 3.0 cable is flat, which makes routing it so much easier. There is no HDD activity LED though, which is rather unfortunate for those using solid state drives, as it is usually a good indicator of whether you system is frozen or just working really hard.
