That's actually a really solid selection of components.
If you can spend a bit more on the case I'd recommend doing so - my personal favorites are the Corsair Carbide and the NZXT Phantom. But the Elite 430 definitely isn't a bad choice at all. Maybe drop the PSU to a TX 650 and spend the difference on getting the Carbide.
I'm not the biggest fan of MSI boards - I've had way too many fail on me - I'd personally prefer Gigabyte or Asus myself. Although I do not like the Asus bulk DVD burners - I had one nearly explode on me, so I generally try to discourage people from buying them.
