Hey man,
where to start? There are lots of good option that would save you money:
- Case: keep the one you have. I have it, and its really good for the price
- CPU: The one you have is good as well, although if you have a microcenter or frys close to you can save around $40 or so
- Motherboard: Get this instead, $20 more, but its very recommended

- Memory: The one you picked is good, but I personally tend to stay away from those tall memory as it causes some incompatability with some coolers. You can still go with what you picked or check this out instead

Also, I would save money and NOT get 12GB. Whatever you do, you will NOT use more than the 6GB already bought. Trust me on this one. You can always get another set if you somehow do realize that you need that
- PSU: The one you picked is a good one afaik, but you can save $30 by going with the Corsair HX series if you want modular PSU for 149.99, or with Corsair TX series if you want to save another $40 and get a non modular PSU for 109.99

Maybe even go for 850w just in case for $159.99 (with $10 promo code available in the link)

- HDD: Again, the one you picked is good, I personally have two myself. However people are recommending the Samsung F3. According to reviews, its faster and cheaper than the caviar black. You will save areound $20

- DVD Drive: I'm not really sure why you went with that really expensive ones. This LG one looks good, and even has lightscribe. It's an OEM though so you might need to get some sata cables and screws (although your motherboard should have extra sata cables, and screws are not necessary with a case like the HAF 922)

- GPU: I would choose the NVIDIA approach instead. For $35 more, you can get a gigabyte GTX 470

or you can go with a 465 as Rydian said, but I still suggest the 470 for that price
- Cooler: Since you opted to go with water cooling, I'll leave that for others to comment on since I know nothing about water cooling (yet)
Some notes:
- Prices are at the time of writing this post. If you arent planning to get them right away, chances are that prices will change
- Whatever parts you finally decide on, check their combo options to save even some more money!
- Some of these items have additional savings promo codes .. be sure to check them out
- Total without combo bundles and additional promo codes, with 12GB RAM and 850w will be $1509 .. minus the $10 promo code for the 850w PSU it will be $1499 .. Check for other savings
Good luck! let us know how it goes
