Switch out that motherboard as you will not be using its main feature of overclocking. You don't need a 3570 either. I suggest this 3470 and B75 combo for
$261. That frees up $90 that you can use towards a stronger GPU like a 7850 to GTX 660 Ti.
I don't recommend going with a SSD either as your only hard drive. You will run out of space very QUICKLY.
Additional case recommendations.
Antec One and
HAF 912.
PSU wise I would look for something in the 500W-600W range. How much do you want to spend on a PSU? This
Corsair 500W isn't bad.
