I read reviews on the case, and the PSU will fit in the case. And I looked for a PSU with less wattage and didn't really find anything on pcpartpicker. Pcpartpicker says that none of the mini itx PSUs are comp atible with thecase I picked out. Doesn't  make any sense, lol.  

And my plan is to use the integrated GPU until I get an actual GPU.

I don't plan on jumping on the SSD bandwagon until they're considerably cheaper. As for the HDD, I had a 1TB Caviar Blue, but a few people suggested I upgrade to the Caviar Black.

I had this build with Intel's 3750k, but that one is only like $2 cheaper.
