Get a 7200 RPM HDD and a 3.5" should be cheaper. (Is there a reason you chose a laptop HDD?) 7200 RPM is pretty much a standard now and it makes a difference for hardly any more. I personally bought a used 1TB 7200 rpm REFURBISHED HDD for $75 on newegg, if you want to go that route. The PSU looks fine but just make sure the load is dispersed across both rails. I have to mention the "Ivy Bridge is newer", but honestly, I really don't see any reason to go with either over the other. But looks great other than the Hard Drive.
