Hi newcomer and welcome to the Tom's hardware forum.
This isn't the correct section for ask about home build system.
What is your budget?
For now, this are my advices:
1- The LCS is for extreame OC, that i think, you will not try.
2- Save the money of the LCS, and get a ASUS mobo or Gigabyte mobo.
3- I would get a 5850 or 5770
4- Get a Spinpoint F3 500GB or 1TB, is better that the WD that you want.
5- The Coolermaster HAF 922 or 932 are a very good cases.
