Case. The HAF 932, this is a big case and to be honest if you are not going to water-cool then I would look for something smaller, Perhaps an Antec or Lian Li or Nzxt to mention but a few.
Mobo. To be honest I would stick with a Z68 as there are few bugs in the Z77 plus there really isn’t a lot of extra value that you can get from the Z77 chipset.
CPU. The i7-3770K. Unless you are a very heavy Photoshop user the gains won't be terribly noticeable over a i5 2500K which is a great gaming chip.
HDD. You have chosen to go the one big hard-drive route whereas I prefer the two smaller hard-drive route, so one can back up the other.
Graphics card. If you make changes to the mobo/CPU/case you could put the extra to a better GPU, whereas your choice is not bad there are many better but obviously cost more.
PSU amd RAM seems fine and the rest of your bits are of course up to you.
