Via processor (~20W) ~$100 (Score 1)

I have a C7 VIA processor board, a GB of ram . The peak power usage is 20W, idle power is 5 W. The CPU has built in sha1/sha2 support for encryption. Its 1.5GHz. The cost of the complete "hack job"; board/ram/enclosure/power was $120. I am using an external hdd to boot up linux - works great with my TV too.
