i5 would be a dead socket soon. i9 release will be on 1366, way to douche your fanbois intel.
To be honest, 720BE is more than you need and it costs half the price, upgrade to a 6 core when they come out.
Personally I would get a seasonic PSU. It might costs a little more but I know i'm getting a good product.
I hate your case tho. I've got one and it's loud as a mofo.
Get a Lian-Li and you will thank me.
