Yup, I second AMD Radeon's point. The TIM that comes with the 212 Evo will work just fine.
If you're interested in saving some money, you can go with a Seagate Barracuda 1tb drive instead of the Caviar Black. You can also get the ASRock Z77 Extreme4 instead of the Extreme6. They both do pretty much the same thing.
And if you plan on doing SLI/Crossfire, I would suggest you up the wattage a bit on your PSU. A 750 watt PSU would be a good safeguard.
