There are small form factor PCs and then there are really (really) small form factor PCs. VIA has definitely unveiled one of the latter class of machines today with its new ARTiGO A1100. The tiny PC has a chassis that fits into the sub-liter category.
As you can see in the image above, the little machine is barely larger than your average mobile phone. Despite its small size, it crams in some nice hardware. The machine uses a 1.2GHz VIA Nano processor combined with a VIA VX855 media system processor.
The PC measures in at 5.7" x 3.9" x 2" and has a gob of connectivity on the rear of the computer. The machine has front and back panel IO ports along with HDMI and VGA out. A gigabit Ethernet port is integrated along with five USB ports, three audio jacks, and optional WiFi connectivity. The tiny little PC would make a mean HTPC at a retail price of only $243 with the fits ten buyers getting the machine for $199.
