I was looking up router information on PC Mag's web site and found this: http://www.cheetahdeals.com/Acer-Home-Server-AH340-UA230N-Facto
link to the server for $250.
Similar Home Servers (WHS 2008) run $400 on New Egg. I think this is a
pretty good deal since building your own as I'm attempting to do will cost
about the same ($250) when said and done. It also has 4 hot swap slots and
the cheapest Mini-ITX 4 Hot Swap Server Case I have found is $180!
This will have lower current draw than using an old PC as a server. I
currently don't have enough cash to pull the trigger on this, but for others
looking for an affordable way to get into Windows Home Server which has way
more options (especially for Windows PC's) than making your own Linux based
server or NAS box for a Windows machine.
