Much like the Carbide Series 600C, the Air 740's interior design presents an unobstructed path for airflow from the intake fans to the exhaust. Unlike Corsair's inverted uber-tower, the Air 740 sticks with a traditional orientation for the motherboard tray and the components attached to it.
The motherboard tray is ringed with nine grommets to meet nearly any cable-routing or liquid-cooling challenge a builder might throw at the Air 740. Three more ungrommeted cable-routing passthroughs provide even more options for solving the cable-management puzzle. Aside from the three 140-mm fans pre-installed in the case, the Air 740's motherboard chamber is refreshingly unadorned, and it shouldn't present any challenges during the build process.
Flipping the Air 740 around reveals its storage and power compartment. The 3.5" drive cage in the upper-left corner of the case can hold three drives on a trio of tool-free sleds. Just above the power-supply mount, a quartet of the snap-together SSD trays used in several older Corsair cases can hold up to four 2.5" storage devices. While these 2.5" sleds don't take up much space all together, unused ones can be snapped off the stack for cleanliness if builders desire.
The 740's vertical power-supply mount uses a thumbscrew-secured bracket to provide extra support and security for PSUs of practically any reasonable length in addition to the traditional four-screw ATX mounting scheme. With that, we've seen the bones of the Air 740—now it's time to put some meat on them.
As one might expect from such a large, roomy case, I had almost no issues putting a system in the Air 740.
Thanks to its entirely open main chamber, putting our motherboard, CPU, and graphics card inside the 740 was a painless process. I had no trouble finding a workable cable grommet for every cord I needed to pass through from the power-supply chamber, and every screw and standoff went into the case without protest. I did run into one small problem with the built-in cabling, however—routing the front-panel connectors through one of the ungrommeted holes at the bottom of the case stretched those cords to their limits. That one challenge aside, the most important parts of our system went in without a hitch.
It's a similar story in the Air 740's storage-and-power chamber. Thanks to the tool-free 2.5" and 3.5" bays, installing our test rig's storage devices was a snap. The only obstacle I ran into on this side of the case was with the 740's adjustable power-supply support bracket. Since that bracket cradles a corner of the PSU, it just barely cleared the fan-mode switch on my SeaSonic SS660-XP2 unit. Not all modern power supplies have this switch, but for builders with units that do, it's worth considering whether this bracket will cause interference with them. With a little convincing, the bracket still slid into place, but Corsair could give builders a little more peace of mind by shaving a few millimeters off the height of that support.
All told, the Air 740's huge size and open design make it a pleasure to build in for the most part. Let's see whether that ease of use is matched by solid cooling performance now.
