Silent NAS/Home server build - suggestions?

[delroth]

So, I've actually changed my opinion on motherboard and RAM: I'm going to go with a more expensive option that supports ECC RAM.

Motherboard: ASRock E3C226D2I (http://www.ldlc.ch/fiche/PB00160259.html)
RAM: 2x8GB ECC Unbuffered (http://www.ldlc.ch/fiche/PB00145033.html)

Cost++, but at least that makes data corruption way less likely. Since I'm going to end up keeping this server for a while, it's probably a good investment.

Also, this motherboard has other cool features: internal USB2 for the OS, 2 1Gbps ethernet, 1 IPMI port (with iKVM!), watchdog, TPM support, etc.
