That is a really good deal. The two things I would change is the video card and (if I'm reading that right) the PSU. Other than that's that's an excellent deal.
yea, very very nice deal IMO, just if this is for gaming, i would get a better graphics card, and one of the best bang for buck cards is the 9600GT. its only $150 AUS in the right places and is almost as good as the 8800GT.
