I kep track on the load on my main server, and it is rarely above

There isn't a good generic answer to your question. "It all depends" on
exactly what hardware you have. A good rule of thumb is 10W for each
disk drive, but some were much higher. Pull the data sheets for your
drives.
A Kill-A-Watt on the power cord is the best way to answer the total
question. My old ancient Dell Optiplex running 5.5 draws about 60 watts
including the APS 350CS UPS. Am not about to unplug it without good
reason:

I found a 10G drive in the trash yesterday. Would one day be a nice
upgrade for the 4G drive in the above.
the datasheets for the 40G drives are lost lost. but what is your
best guuess about my old 1998 HP's (400MHz) compared to a newer,
generic 1.8GHz processor? IIRC, my AMD 2.8GHz uproc sucks up
around 75watts; the Intel was maybe 35w.
If your serious about power but need newer capacities, I'd look at
something like http://www.wdc.com/en/products/greenpower/index.asp and
maybe an intel atom (or after reading the reviews/benchmarks the via
nano when its available.)
With dual opterons at the moment my load average (except for when
compiling) is 0 - 0.1 but my electricity bill is significant so i'll be
looking into something atom/nano based in the near future, especially
when i can get a motherboard with CPU for less than 60 uk pounds.
