Best cheap CPU's for custom NAS?

[Rekcut722]

What's the best low power cpu for use in a custom nas? I'm looking at old xeon's and server hardware, so used stuff is fine. I'm also trying to keep costs as low as possible. I have been able to find old xeon quad cores at 3 GHz for like $10 a chip but nothing low power enough for my needs. Since I probably won't even be running windows on it, dual cores are the minimum I want to have and clock speed doesn't have to be anything high, but should be good enough that it's not a bottleneck in any way. Any suggestions?

a xeon e5000 series chip is a great price to performance chip for projects like these. I recomend a xeon e5420 or e5620. But if you are looking for efficiency then look for low power xeons from the same or similar year.
