What kind of processing does the NAS server really do? I mean, it won't 
do actual calculations / DB access / etc, those will all be done by the 
host OS / server, right?

For the price difference, the bigger CPU is a better investment, which 
could also be reused for something else (xen server?) if this doesn't 
work out. Unfortunately, the only ECC capable motherboards I can get my 
hands on will be XEON, which is much more expensive than a normal 
desktop type motherboard. And the CPU's will cost more.
