The Gigabyte board would give me enough SATA ports and grunt to run a decent NAS - I think it'd give the C2750 from Intel a run for its money, power wise.
Your linked article has a comment suggesting the Gigabyte board retails for 987 Euros. Jeebus.

It's dirt cheap ($10-20), easy to load linux on [1], and it can be a simple file server, it can run minidlna, google cloud print [2], all kinds of stuff. 800MHz is not a screamer, but most simple I/O tasks like A/V streaming and printing are a walk in the park.
