The CPU. The i3-2100... You can get an i3-2120 that is a little better for roughly the same price. Its worth it.
The Power Supply. Quite frankly, CoolerMaster sucks for power supplies. They do have a few decent models worth considering, however there good ones have better ones from more reputable brands in the same price ranges. CoolerMaster also has a history of deliberately lying about the capabilities of their power supplies. Stick with brands with better reputations like Corsair, Seasonic, Antec or XFX.
Also, I would consider going with a 6870 video card instead of the 560 non Ti.
