Yes I didn't speak/type correctly. But my frontend's aren't MythTV
frontends, I prefer XBMC, but I have mythTV backend servers.  So not sure
if the same writing data into the database.  Anyways, I do try to use the
shutdown command with the remote, sometimes don't remember and just pull
the plug on AppleTV or w/e.  My main concern when I started this topic was
startup on power insertion, not really power down.   Not going to go more
into it.   Anyways, TY to the people who got me the BIOS settings for it.

 I've ordered it, $20.  So we'll see if I can figure something out for
heatsink/fan from the junk laptops my father for some reason keeps, and
some sort of case.  Appreciate the responses.
