Odds are this would be a little bit of a hardware mod.  Get a 
microcontroller and a relay, and tell the microcontroller to kill power 
to the system.  Make sure in the BIOS you're set to restart when the 
power comes back on.  If that fails you'll need another relay to short 
the on button.  I don't know of anything in the computer that could be 
easily used instead of a microcontroller.

You might be able to find something that'll work related to home 
automation.  But the only guarantee of a power down is physically 
killing power, even if you're a thousand miles away.
