I'll be interested to see what my new machine (Athlon 2800+, 
.5GB RAM, 2 200MB Maxtors and 3 PVR-250 cards) will suck 
down.  The Kill-a-watt is waiting. :-)

Well, you could move.  Not all states have the stupid enviro 
laws like the PRC does.  I pay < $0.065/kw in Nebraska.

That might be the problem.  3 drives spinning constantly 
will use a fair bit of juice.

Somewhat high, especially for a Tbird.  A 1GHz Tbird uses 
about 54W.  If the core voltage is the same, then your 
1.3GHz shouldn't go over 60W (guessing), if the voltage was 
dropped by AMD then it will be less than that.

 From what I remember Intel CPUs use a bit more power than 
an AMD for the same performance.  But I never have paid 
attention to Celerons.
