What’s immediately striking about this case is the colour matching between the plastics and painted steel, which is exceptional. In our white review sample, the white with grey accents and the odd little flourish of Corsair yellow go so well together, and there are little details all over the case that make it feel a cut above.
Less class-leading is the front panel connectivity, with just single Type-A and Type-C USB ports and a combined audio jack, with no adapter provided to split the latter. The power button has a satisfying resistance to it, though.
The glass side panel uses a combination of push pins and thumbscrews on the rear edge, to give it a clean frontage. The rear panel feels a little flimsy though as it doesn’t have much in the way of reinforcement. The motherboard tray too has a fair amount of wobble, owing to the ginormous CPU and cable cut outs.
The Corsair’s cable cover looks good but isn’t so practical. The gap between the motherboard tray and cover is tight and requires the 24-pin cable to bend around on itself in a very short distance. It’s fine with flat ribbon cables, but the bundled cables on Corsair’s own PSUs struggle. It can be moved forward by 20mm for more room, but this creates a more visible gap.
The pre-fitted cables are very neatly managed but the plastic trays they’re Velcroed into aren’t so good at accommodating the rest of the system’s cables, instead just getting in the way. Good job there are plenty of other cable tie points located all over the motherboard tray.
One nice design touch is at the top of the motherboard tray. The cable cut-outs start in the motherboard tray, but continue when the sheet bends backwards, providing ample room for the EPS and fan cables.
There are two 2.5in drive sleds mounted on the back of the motherboard tray, which can also be mounted on top of the PSU shroud. Under the shroud is a cage that will take two 2.5in or 3.5in drives. The plastic sleds in the drive cage are quite loose though and have no vibration dampening, causing quite the racket with spinning storage media.
The 4000D is one of the more watercooling-friendly cases, taking up to a 360mm radiator in the front and 280mm in the roof. It also features a built-in vertical GPU mount, but do not get tempted to use it with an air-cooled card, as there’s no room for the fans to breathe.
The two AirGuide fans included with this case do a great job cooling our new rig at lower noise levels, being quiet enough to run at nearly full speed for the 35dB test, coming first overall in that test and being the quietest at full speed at 35.9dB.

Corsair 4000D Airflow review conclusion
The case that started Corsair back on a fine run of form is still one to beat. It’s got the looks, performance and build quality to match anything in its price range. It’s not packed with dazzling features but is a solid work horse of a case that’s relatively quiet too. We like this case so much it made it into our best PC case list.
Stylish, quiet and with excellent cooling. What more do you want?
