As long as your PC is configured correctly, there's always juice running through there. Then, you just use a relay to trip the power button contacts. Heck, you could even pull this off over long distances using a cell phone...
I don't have any ready-to-go receivers or transmitters sitting around at my place... what I actually need is a proper schematic so I can design a custom PCB for the transmitter and build the corresponding receiver circuit to integrate into the PC.
