I want the same thing except for servers.  I would love it if there was some way 
to reduce power consumption for disk drives but I think the easiest thing would 
be to scale back the CPU clock rate during times of low load which would reduce 
a major source of heat and between that and high efficiency power supply units, 
that's the best we are going to get for awhile.  Even still, it would be great.
