I've got a cunning plan to minimise the electricity usage of the file
server (and other gratuitous machines) in the house I'm moving into next
month...it involves wake-on-lan, a router capable of waking devices at set
times (i.e. one with custom firmware) and a scheduled shutdown...I'll see
how much oomph it actually saves using m'digital power meter and let you
all know if it works + is worth it.
