[GLLUG] Low-power Home Server

[Tom Schouten]

Hi List,

Recently I've been doing some math and found out that running a 100W 
machine 24/7 at my parent's back home cost me about 150 Euros/year 
(Belgian electricity is quite expensive, about 20 Eurocents/kWh more 
than double of what it is here).  The 100W was measured with power meter 
over period of 24h so is probably quite accurate.  Includes PC, GB 
ethernet switch + wireless router.

Anyone have an idea of how to replace this with something more 
power-efficient?
I recently ran into [1] which seems like a nice solution.  Not sure 
about the power though.
It probably can go lower still.  This[2] might be nice too.

The main purpose for the server is backup, VPN, asterisk, email with 
spamassassin+clamav, apache and to serve as print server and gateway for 
the home network, maybe also PLEX but that can also run on a "real" PC 
if necessary.
