I'm not an expert on CD drives but it looks fine. Though you can always get one from your old machine
get the "BIOSTAR T5 XE CFX-SLI LGA 1156 Intel P55 ATX Intel Motherboard" because the other one might be a bit hard to assemble (smaller size for smaller cases, but still fits)
Intel range isn't my forté, because it makes no sense

but I imagine you want to spend as on the processor as the graphics card. In my experience games like crysis benefit more from a better processor than a graphics card
The ram isn't enough to give that system justice, perhaps
"Geil 6GB DDR3 1333 CL9.0 Triple Channel Black Dragon" might be nice?
$42 is a low amount to spend on a gaming rig for RAM anyway
My general advice? Graphics cards are over-rated in terms of overall system performance, and the processor and RAM won't let you make good use of that card. I'd spend less on the card and more on the other components I mentioned
