1. For gaming today, a 3570K will be just as effective as a 3770K. Use the $100 saved elsewhere.
If you can wait, haswell will be here within a month, look for the 4670K and a z87 based motherboard.
2. For a single 1080P monitor, I would go with a strong single gpu. A 7970 or GTX670/680.
Look for the upcoming GTX770 or 780 card.
3. I like 16gb, even though you wil use only 2-3gb for gaming. But buy a single 16gb kit of low profile 1600 ram( 2 x 8gb).
4. Why 3 hard drives? I would buy a 240gb ssd, and a single large storage drive.
5. In a well ventilated case like yours, I would go air cooling. Look for a Noctua NH-D14 or phanteks. Liquid tends to be noisier, more expensive, less reliable, and does not cool any better. There qre too many tales of woe when a liquid cooler leaks and destroys everything.
6. Coolermaster psu's have iffy reputations. Look for Seasonic, Antec, Corsair, XFX
Here is a quality tiered list:

7. With your budget, I would look for a IPS panel monitor. Look for a 178/178 viewing angle.
Better yet, look for a 1920 x 1440 27" monitor. It is one of the few future proof pc purchases you can make today.
