I think you have a pretty solid system there, except for the CPU personally it wouldn't be my first choice and I recommend Mushkin Ascents over the Corsair ram you might find their a little cheaper but perform just as well. Try to find some cash your in budget for some addtional case fans and seriously consider an alternative to the stock cooling that comes with the Intel CPU. Possible suggestions are the Sunbeam Corecontact or the OCZ vendetta2, both come with fans and they are reasonably priced.
A core i7 cpu, motherboard, and memory alone would probably be your entire budget.
