i used the vortex 211p before. not much diff in performance to stock cooler. get those cheap hyper series will be good enuf.
for ssd, if wana save money, i suggest go for 128gb and use savings get second hdd for large files. ssd will be good enuf for OS and a few games.
since not OC, go for cheapest i5. u won't tell the difference for normal tasks. mobo depends but i like the asus bios. user friendly. if budget conscious then go for asrock.
win7 is an old os. so there's a lot of info on how to get it free. google it.
for gpu, amd will give better performance and cheaper but at the expense of higher temps and power consumption, if tat bothers u. go for at least 500w onwards.
