If you plan on overclocking you will need an aftermarket CPU cooler. If you are going to overclock, I'd recommend getting a quality PSU 50-100 watts over the recommended system wattage from Seasonic, XFX, Corsair (except their CX series) or Antec.
Also, I recommend you verify your selected RAM is compatible with your motherboard. You can do this two ways:
1. Go to the motherboard's webpage and check its QVL for compatible memory (QVLs do not necessarily list all compatible memory)
2. Go to the memory maker's website and use their RAM configurator program/app, just tell it your motherboard and it will list all the compatible memory that they make.
