Thanks to Azulle for providing the Byte3 for our review!

We'll start with a quick look inside the box:

The Byte3 has a small, rectangular form-factor of some 5.6 inches wide and 4 inches deep, with a height of 1.5 inches.

The Byte3's enclosure feels very well made, and has a nicely finished appearance. The only disruption of the low profile form-factor is the rear-mounted antenna, which should help provide better Wi-Fi reception.

I/O is good for a mini system, beginning on the right side where there is a standard SD card slot and one each USB 3.0 and 2.0 ports.

On the back, left to right we find a 3.5 mm audio jack, two more USB 3.0 ports, Gigabit Ethernet, HDMI, VGA, and USB Type-C.

The other side of the Byte3 offers some ventilation

The top of the device is a metallic material that is part of the heatsink:

From the bottom there is access to the system board – and the storage upgrade options – by removing the metal plate.

Next we'll take a look inside the Byte3 and then check out the results with some performance benchmarks.
