My uses for it will be all-round, including gaming. gaming will probably be the most intensive use as i dont video edit or 3d model or anything like that.

(1.)
first of all my current pc is this:

instead of building up from scratch, could i just replace parts out of this old case and retain stuff like HDD and optical drive?

(2.)
I'm already set on the PSU and GPU

PSU: corsair cx430 ~$40 with rebate
GPU: GTX 650 Ti Boost or 660, (whichever is price efficient or on special deal) ~$200

could you recommend a good combination of CPU+cooler, mobo, and 8gb of memory to go with this? preferably for ~$300 and without bottlenecking the 660

(3.) did i leave anything out?

(4.) would you do things differently? (suggest better options for PSU and GPU, adjust budget etc.)
