Hi,

maybe write your hw configuration first. Eg: CPUs, graphic cards, HDDs
(size, speed, type) and others. 

Also provide lspci output and /proc/cpuinfo.

Then this is a server, maybe with more than one GB nic. If you dont use
spare nics disable them in bios. Do the same with other unneeded stuff.

If you can access your server and replace cards, remove everything you
dont need. Do not lower fans or dont play with cpu voltage. If you want
to run this server 24/7 it can cause serious problems. It will not save
you much power. Paradoxly this could lead to higher power usage in
some cases, because of hotter devices.

Remove spare memory cards, if you dont need much memory, etc.

Robert.
