The Carbide Air Series 540 is sort of like a "double-wide" in nature; it's got a separate compartment for the power supply and drives hidden behind the motherboard tray, making for a cleaner install and future management. Theoretically, this also reduces thermals by spreading the components out some more. Externally, the effect of this design choice makes the case slightly resemble an accordion. We have 2x140mm fans in the front of the case, 1x140mm rear fan near the CPU, and no fans in the rear compartment.
For drives, we have 4x2.5" internal bays, 2x3.5/2.5" hot-swappable drive bays, and 2x5.25" external bays. The hot-swappable 2.5/3.5 bays are located in the motherboard-side of the case, toward the bottom.
