All of those components are great. The only recommendation I have is purchase an SSD instead of the 1TB Caviar Blue. The Caviar Blue drives have a smaller cache, so your performance would be impacted on initial loading and during texture fetches, and a shorter warranty of three years. Go for a 250GB SSD or more, both the Samsung EVO line of drives and SanDisk Extreme and Extreme 2 SSDs are excellent performance and very well priced. You can always get an inexpensive WD drive for long-term storage later on. A very good 2TB Caviar Black from WD would set you back only about 100GBP and comes with an excellent 5-year manufacturer's warranty.
