CPU-performance-wise, I am not really worried. The current system is
an Atom 330 and even that is a bit overkill for what I do with it and
from what I am seeing, the new Atom D510 used on those boards is a
tiny bit faster. What I want and care about for this system are
reliability, stability, low power use, quietness and fast disk
read/write speeds. I've been hearing some praise of ICH9R and 6 native
SATA ports should be enough for my needs. AFAIK, the Intel 82574L
network cards included on those are also very well supported?
