Loosen eight thumbscrews, release some clips, take off some panels, and the Air 240 is open to the world.
The motherboard chamber is simple enough. Corsair's usual rubber cable grommets abound, and there are sets of grommets for both Mini-ITX and microATX motherboards. Pre-installed standoffs are at the ready for motherboards of either type, too.
True to its name, the Air 240 has room for lots of fans. The case comes from the factory with three fans: a pair of 120-mm intakes at the front and a single 120-mm exhaust up top. Builders wishing to add more fans can put another 120-mm unit up top, two more 120-mm fans on the bottom of the case, and another pair of 80-mm blowers on the rear wall.
Unfortunately, there's not a lot of room for tower-style CPU coolers in the Air 240. The case can take a 4.7"-tall unit at most. It's good that the Air 240 can accommodate large liquid coolers, then. The front wall of the case can handle radiators up to 240 mm long, and if you're willing to use a Mini-ITX motherboard, the bottom of the case can accept another 240-mm heat exchanger.
Moving around to the power and storage chamber, there's room for three 2.5" drives and three 3.5" drives—as well as for PSUs up to 8.9" (or 225 mm) in length. For perspective, Corsair's beefiest PSU, the AX1500i, is about 8.9" long. Mere mortals should have no problems fitting their PSUs into this case. The PSU mounts are topped with four rubber discs, which should help to minimize noisy vibrations.
Removing the right side panel alone doesn't grant access to the storage bays. The 2.5" drive cage is covered by the top panel, while the 3.5" cage is protected by a hatch at the rear of the case. The complexity of this arrangement is a little annoying, but I don't see any other way Corsair could have placed the drive bays while keeping the Air 240's compact dimensions.
Each drive cage contains three tool-free drive sleds, which are dampened against drive vibrations by rubber isolators.
With all of its panels removed, the Air 240 is ready for a system. Next, I'll install our Casewarmer build, and we'll see whether the Air 240 can keep it cool.
