Pretty nice build. The 212 evo comes with a little tube of thermal paste but you have to apply it yourself which is easy. I'm using my 212 evo for now until I get my h220 back from rma after it fried with the rest of my comp but the 212 evo is a very good cooler for dollar. In my opinion you wont need 1866mhz ram if your just gaming but 8GB of it is perfect, but you will need low profile ram like BlackOutCrisis said.
