250W is already pretty high, i think you can get away with 150-180W for that machine and 4 disks, which would bring costs down to ~$180/yr or $15 a month.

If you just need media storage an atom or similar cpu will work, but if you need/want to run a couple of VMs a Server like this one is the better choice.
