<2000$ Gaming PC - First Build - Need Advice

I've owned overpriced prebuilt gaming systems for years due to a family connection to Dell and after frustration with them and Alienware I've finally decided to take on my first custom build.
I'm looking for a top of the line system with room for upgrades down the road.
Currently in the rough draft stages, will be purchased ~1 month from now
----------------------------------------------------------------------------------------

System Use: Gaming first priority, IDL Computation and some programming work secondary

Inherited Parts: Antec 1000W psu from previous Alienware system
2X 320gb seagate 7200rpm storage drives
120gb OCZ Vertex 2 Series ssd for OS and programs
24" 1920X1200 Samsung 245bw monitor

Build:

Case: Antex 1200

Size and weight not an issue for me, liked the look of this case and I will be adding in a fan for the side slot initially. Would like to look into watercooling later on (complete beginner on that front, appreciate any recommendations).

Motherboard: EVGA X58 FTW3

Always loved evga boards, and this one seemed to offer decent OC' support, I don't mind the price for the sake of future proofing but if there are more stable boards with similar feature sets, am open to suggestions

CPU: I7 950

Would like to overclock to at least 4 ghz, on air initially if possible, any recommendations for a good HSF or intro level closed circuit water cooling system appreciated

Memory: Corsair Dominator 3x2gb DDR31600

Room to upgrade to 12gb later if the system needs it

Graphics: EVGA GTX570

Plan on another 570 in SLI when the first card begins to get taxed or if I decide to upgrade to a 3d monitor setup

Overclocking: I plan on OC'ing the cpu, it will be a 24/7 unit however, so stability is paramount.

Cooling: As stated above, I plan on working with air cooling initially, but I would like to setup a watercooling system for the cpu and the graphics cards later on, especially when I get to the point where I have two 570's in SLI.
Noise level is not too significant of an issue, but I don't want this thing to keep me awake if it's idling at night

Experience: As I stated above, I've been using prebuilt gaming pc's for about 8 years now, and generally know my way around a computer. I've performed upgrades on several and am confident with putting a basic system together. However, I am still a relative beginner in terms of overclocking cpu's and memory and cooling systems.

Live in the US and I prefer using newegg for parts.
Using newegg, the parts above (for the initial build, solo graphics card on air cooling) came out to just over 1200$, however this does not include a quality cpu HSF which I need recommendations


If there's any more information I can provide, please let me know.
