Not immediately handy, but the two devices that I used are from a few years ago. Maybe these model numbers have been deprecated for newer hardware. Sinilink PCle Computer Remote (XY-WPCE) Sinilink USB Computer Remote (XY-WPCL) If you have the space and a spare PCI Express slot, I suggest going that route just for the slightly tighter integration; if memory serves, there is a always active 3.3 volt supply as well as a way to infer if the PC is awake or not. You still need jumper wires off to the front panel header though for power and reset purposes.
