Spec build for a friend :)

My mate wants me to build him a pc ... His max budget is £650 , going to be used purely for gaming. He just needs the tower please, he's god a cd drive and wifi adaptor.. He does need an os though if possible .

Thanks in advance

Cheers both , what's that i3 like ? Not read much about them, I'm guessing that's going to be the best option with his budget ?
