I have a shuttle sk43g that I just setup with a hauppauge and firefly remote, that I built as a HTPC. I can shut it down without getting up but how do I turn it on without getting up. It pumps out too much heat to leave it on all the time.  
Any ideas?

You could try this:

hope this helps.

Enqble "wake on LAN" and ping it

 
 
Or get an old shoe, aim for the power button, throw and pray.
 

 
 
I used to use a snooker que, but only had so far it could reach.
 
 
Cant you simply set the Firefly remote to hibernate with power button press. Then it should be able to wake again with another press?
