When quoting, go to the very end and start typing
I got confused.
Anyways, just change the HDD to a $55 barracuda (pcpartpicker glitched I think), change the MoBo to a Extreme3 (There is very little difference, not even noticeable tbh), consider changing RAM to a 1 x 8GB from Axevir, and you'd be just under budget I think
(yes, I know the RAM is slightly slower, but he can OC it, and latency isn't THAT noticeable tbh)
