Another point to save, if your computers are running 24/7 and mainly provide 
server functions and you are not frighten to run Linux, which I guess is the 
case for a gEDA reader,  

a) just buy a bigger machine and use virtualisation technologies like XEN, 
Virtualbox, VMWare, etc.

b) get some of this little ARM based boards or Atom based boards to replace 
your hungry desktop processors by something more greeny (e.g. check for the 
beagle board on the web which consumes only 1.5 W). This yet tiny but powerful 
systems can normally serve well all home and small office network and multimedia 
stuff and requires less power in full operation mode then many desktop 
computers in suspend mode.
 
c) Computers which does not need to run 24/7 but always on because of the 
discomfort to shut them down and power them up will benefit greatly from wake-
on-lan and wake-up-timers (mostly found in bios settings).
