I've got quite simple question actually. How green, low-power and efficient x86 home server can I build using consumer parts with rather constrained budget.
After looking through some Google hits I've found out that system based on dual-core atom, some modest mITX board (gigabit lan, integrated audio and gfx etc), one RAM module and one 'green' WD HDD, powered by picoITX PSU uses about 30W at idle up to 40 at load.
Can you get lower (or how much lower) then that? Maybe some VIA nano chips, or single core atom?
My home server would take care of some back-upping mixed with little ftp/http traffic.
