Heh...seeing this thread reminded me that I need to do this myself. Mine are on 24/7 except for the monitors. Need to verify just what these things are doing as I think it costs me probably $100 extra here, too. :P

I will not be doing the sleep/hibernate thing, though. Power management is way too buggy for daily use for a gaming rig, IMO. And it usually manifests itself as weird intermittent bugs that are a PITA to lock down. Better these days than it used to be but still not something I want going on if I can possibly avoid it.
