They are now.  It took three reinstalls of the BIOS upgrade before it 
took control of all of the ancillary stuff.

I also found that switching to DVI from HDMI (the box is connected to 
our flat screen TV) made the video card fan run a bit quieter with a 
decline in video output quality, as well.

I am a member of the "red screen, bad, blue screen, good" school of 
monkeying around with CPU settings and this produced more red boxes on 
screen than my personal bottle will hold, so we're still on "optimal 
settings" for the CMOS.

The USB drives all seem to have a feature of this type and I have looked 
at seeing how this can work on a torrenting box that can be accessed at 
random times.

Thanks.  I am now looking for a frame of reference can fit these numbers 
into ...

That was helpful.  I am still looking for an answer on how I should 
calculate average and high load but my Googling doesn't produce any 
majority opinion.  I "feel" as though I should be taking some percentage 
of max load.  Dragging out and opening by Bosch Automotive Handbook, it 
looks as though watts are added together, right? ... So the real issue 
is deciding the average load ... somehow?
