Really? Even a meaty 3.5" drive will be less than 10W, and you're between 4
and 5 for a low power unit. Something like a 1Tb Samsung Ecogreen is around
4.3W. The CPU in the system is going to draw a whole lot more than that. But
face it, if it's just acting as a router, it can completely spin that down
after boot anyway.
CPU and motherboard contribute a fair whack to the power consumption.
I've no specific recommendations, but clearly something like the following
gets you close.
Get the gold board and you've got twin 10/100Mbit network, 128Mbyte RAM,
various ways of connecting extra storage, and a 2.3W maximum power draw.
That compares rather well with the old Pentium 4 you're likely to have
knocking round which draws about 70W typically just for the CPU...
