I picked the parhelia because of it's ability to drive a TV and two monitors at the same time, and it's a bargain at $74 . This machine just chills in the den, no games, etc... but I do save movies from my PVN card to that huge Hdd. No important data, etc, just PVN'ed monies.
The k7n2 is fine as long as you don't plan on running linux
:-P
