If possible maybe stretch the budget and get a GTX670 or ATI equivalent.
Even if you plan to overclock a small boost in CPU won't require a cooler.
They can easily overclock 600Mhz at least on stock voltage.
PSU is overkill... Unless your planning to do SLI or Xfire but with your budget I don't think so
(I'm running a SLI GTX670 on 550w Platinum power supply
trust me!)
Case: Antec 302 is a bit smaller but very sturdy and nice case. One of my favorites.
Memory: Just to save a few $$$ because it won't make a big difference anyhow.
HDD: Do you really need a 1TB HDD? You can always upgrade to more space if you want, so why not start with 750GB? Save $$$
PSU: 400W is plenty for a complete setup with videocard. My old overclocked Q6600 (power hungry) and 8800GTX only used 250W under 100% load (furmark and prime) So I doubt that you will need more than 400 with a 560Ti or GTX670.
Good luck
