Most energy efficient (home) setup

I've run a SheevaPlug at home for a few years now.  I don't do
anything fancy with it, but it does what I need it to do.  Mostly that
is file server, web server, jump-box for network testing.  Also
testing different linux software for this and that...  (Quagga runs
nicely, but won't hold a full BGP table :)

There are no moving parts in my home computer/networking gear, unless
my laptop is running.  That was the goal for me.  I recently grabbed a
couple of TPLink WR703N devices to mess around with as well, but I
haven't had a chance to dig into that much.

The internet tells me that the Sheeva uses about 5 Watts of power.
Along with my wireless router and DSL modem I might be under 10 Watts,
but I really don't know how much power a wireless modem uses.

Oh and I also have native IPv6 on my DSL.  I like to brag about that
whenever I can.
