Thanks, chucke - I appreciate the kind words!
Randy, if it were my system, I would buy a much larger 7200 rpm drive for the C:.
If my memory serves, I believe all the Thermaltake cases are pretty well-insulated (one of their major selling points), which is another good reason to considering the method of cooling (# of fans, etc). I don't think you need to go to the extreme that many gamers do when over-clocking (getting an expensive liquid-cooled rig), but you do need to be cautious.
Other than that... let us know how it works!
