The Airbox USB 3.0 ships with AC adapter, USB 3.0 A-B cable, mounting screws, screwdriver, color user manual and stand.
USB 3.0 cables are only compatible with USB 2.0 on the A connector, which is identical in shape however internally contains twice as many pins. The B connector is a new shape that stacks the additional four pins in a separate section on top.
The Airbox housing contains an 8cm cooling fan on the side, with exhaust holes on the rear. This end also contains the AC power jack and switch, the USB data port and an on/off switch for the fan LEDs. The other end is blank except for an LED strip to indicate power and drive activity.
Next up, installation.
