We’ve seen Power-over-Ethernet used to allow network CCTV cameras and IP phones cut the AC cord, but a full PC is somewhat rarer. SkinnyBytes new touchscreen Windows 7 all-in-ones can run on less than the 30W of power PoE 802.3at supplies, thanks to Intel’s Atom CPU range and passive cooling.

Despite the frugality, the machines are still reasonably specified for nettop-style AIOs. Both 15.6-inch and 18.5-inch desktops are available, each with Atom D510 dual-core CPUs, 2GB of RAM, a 40GB SSD (80GB optional) and GMA 3150 graphics. Connectivity includes four USB 2.0, a VGA output, multiformat memory card reader, audio in/out and gigabit ethernet. No WiFi, but since you’ll need a wired ethernet connection for power that’s probably no great loss.
The 15.6-inch SkinnyBytes AIO kicks off at $899, while the 18.5-inch SkinnyBytes AIO starts at $999. The company also offers PoE touchscreen laptops, which charge via the ethernet connection rather than an AC adapter.
