Xi3 Corporation recently announced a new small form factor computer with the Xi3 Z3RO Pro. The new PC features a blue and silver chassis in typical Xi3 styling. It measures 1.9 x 4.9 x 3.6 inches, which is about the size of a small paperback book.

Inside the chassis, the Xi3 Z3RO Pro features a dual core processor clocked at 1.65GHz with 2MB L2 cache, a GPU with 80 shader cores, and 4GB of DDR3 memory. Further, Xi3 will include between 16GB and 1TB of internal storage. The system will reportedly operate on a mere 15W.

Rear IO on the Xi3 Z3RO Pro includes four combination eSATA/USB 3.0 ports, a single Gigabit Ethernet jack, and two video outputs. It has one combination HDMI and DisplayPort output and one mini DisplayPort port.

The low-power system is available for pre-order now. It will officially launch in the second quarter of 2013 for around $399. The Xi3 Z3RO Pro ships with OpenSUSE 11.2 Linux, but the X86-64 compatible hardware will support other desktop operating systems like Linux Mint and Windows 8. Unfortunately, Xi3 was vague on the processor being used, but an AMD APU of some sort is a good bet.
