Re: Re: Modern Home Servers - Power Savings

["Jon Wilkins" <jonpdwilkins@xxxxxxxxx>]

Like Paul, electricity usage / running costs is important in my design
too.

Fortunately my requirements are not resource intensive so my new server is
based around a low consumption mini-itx epia board consuming approx 30w
including HD.  My initial estimates reckon about =A330-=A350 annual cost
fo=
r
24/7 running.

Of course there are compromises to reach this - no raid/online backup but
I'm intending to do automated off-line backups to an external drive with

server controlling power up/down as needed.
