UK firm DSP Design has made a PC that gets electric power via a network cable rather than through a wall socket.
Before now power via a network system has only been used for devices such as wireless access points, CCTV cameras and (Voip) internet telephone handsets.
DSP said it expected their new PC to find uses where it was hard to lay any kind of cable other than computer network cables.[1]
How cool is that? Just make sure you don't stick the ethernet plug in your mouth, I guess.
