1. R4. Good case evolution from SPCR Recommended R3. Quite large though, but that's what you get if you have to go full ATX. (why not mATX?)
2. 3570K. Good value for overclocking, good for gaming, wouldn't hesitate.
3. Gigabyte has had poor fan control so far. I would go Asus for Fan Xpert 2 or Fan Xpert+
, as pointed out earlier.
4. Noctua U12P SE2 will be plenty, alternatively I would suggest the Thermalright HR-02 Macho
. Great value, beats the D14 with dual fans, no RAM issues, excellent for low airflow (silence).
5. GPU definitely overkill for such a small resolution, the 660 Ti
is much more appropriate, as pointed out earlier, and since cost is apparently not a problem.
6. I have the m4/128. Love it. I've built rigs with the Samsungs and they have been lovely as well. Crucial's firmware updating has been slightly easier.
7. No SLI necessary, Ivy Bridge CPU, overclocking... no more than 500/600 W PSU (go Gold or Platinum, since money is not an issue)? See this chart here for reference
- the overclocked 660 Ti with overclocked Sandy Bridge EE (130 W TDP vs 77 W for the i5-3570K) CPU was pulling 434 W only in a real-world heavy gaming scenario. Maybe the recently SPCR reviewed Enermax Platimax or Kingwin/Superflower LZW? I like Seasonic, but have had buzzing samples from them.
. No contest. Blues are legacy drives with no real advantages between Blacks and Greens - and now Reds.
9. Ripjaws fit fine with the Noctua U12P SE2, had some in my old setup, should fit even better with the Macho. I use Snipers (low voltage) from G.Skill now. For overclocking, the faster the better, but the price cutoff (value) comes around DDR3-2133 or so.
10. If you have it already, why not. I like Pioneers best, smooth rumble instead of buzzsaw.
Why not go mATX? If you only have SLI (although it would be a waste of money for you at that resolution), you'll have two cards, and you can get SLI boards in mATX. Compact cases are lovely to live with, and these days they're clever enough not to hinder the assembly process or maintenance. I absolutely love my Define Mini (after using a P180B for many, many years), even if it's not the smallest example.
