If you want to overclock get the sunbeam core contact freezer and mounting bracket(sold seperately) if not then you are fine.

The corsair 750TX is more power than you need which is never a bad thing

Now to the Operating System. My suggestion would be to download Windows 7RC and then buy the full version when it comes out. You should get the 64-bit version, but if that is too much of a chore, then go with Vista Prem. 64-bit.

Hope this helps you out.
