I have been doing these for years as DIY. In fact some of my "corporate" IT collegues are bound to shiver with "non-compliance" jitters when reading this article.
In any case this is an area where Via has always been extremely good. For example in 2001 it was doing 2-3 times higher disk access speed than a dual CPU Xeon (Intel OEM motherboard) with price per IOP difference of nearly 20 times. While Intel has improved considerably Via can still beat it in this area due to much lower prices (though Atom has probably evened up things quite a bit). Though even in that case Via has an ace up its sleeve. You can have an encrypted array "free of charge" - CPU support for crypto.
So, what is the price on this box?
