On the outside, the NAS 3.0 is identical looking to the NAS 2.0 except Addonics has gone for a dark blue coloured body versus the black design of the NAS 2.0 (at least I can tell them apart that way!). Ventilation is provided through some openings in the recessed lip on the top of the NAS 3.0 as well as though some ventilation slits cut into the bottom. Since the NAS 3.0 doesn't contain any hard drive, it really doesn't get too hot to begin with.
On top, three LED lights indicate power, system status and system access.
The left side has two USB 2.0 ports - one for your storage device and another for a USB printer. Each port is labeled in the plastic just above the port. Despite the NAS 3.0 name given to this rendition of Addonic's USB NAS product, it doesn't signify USB 3.0 unfortunately - only that it's the third revision. Given the release timing of the NAS 3.0, it is a little disappointing to see no USB 3.0 support yet as that would really take the performance of this NAS to the next level - although it might sacrifice a bit of the lower price point too.
The right side is where you'll find the gigabit ethernet port, a small reset button and the AC adapter connection. The included adapter is very compact and plugs vertically into your outlet so it will only consume the space of one plug, even on a crowded power bar.
