Skip the CM heatsink for this Thermaltake Frio for $5 more. It cools a better, and Newegg has not jacked up the price $20 above suggested manufacturer's retail. Have trouble believing they are gouging like that.
Upendra09 is right about the WD Caviar - it is overpriced compared to the SpinPoint F3. I disagree with the extra RAM - It will generate extra heat and draw more power when overclocking. You will get better results with 4GB
