i got everything picked out except your mouse/keyboard, dunno if you even need that...or what you plan on doing with this machine. but heres the rundown
Notice i only went with 1 video card...SLI honestly isnt gonna do much for you, not really worth the extra cost/power it takes to run it. Also with that video card you get a combo deal with another part, not sure which one
edit: also i didnt pick out a CPU cooler. the one that comes with the CPU will be fine unless you plan on overclocking.
edit again: scratch that DVD burner, its IDE, which is basically ancient these days...i'd go with this one

Its a samsung 22x SATA burner, only a few dollars more and way faster
