This seems to have worked. Will give a it a few days and a few more 
recordings/shutdowns before I call it a complete success.  I wasn't 
around around the time it went to sleep, so I'd like to be around the 
next recording to see it shutdown on it's own.  That said, it wasn't 
shutting down on it's own before after long periods, so this should be 
considered a minor success.  The main reason I wanted to do this is 
because the fans on the two CPU's, the case fan, and a possible HD cage 
fan, right now give my SBE it's hostname of ENTERPRISE(after the USS 
Enterprise, aircraft carrier). This thing is rather loud, plus it's nice 
to put it to sleep to save some power. I have plans of replacing the 
fans, but not right now[hopefully then it'll get that name only for the 
size of the tower then].
