I wanna try my hand at building a computer for the first time. My old computer is really only collecting dust so I want to use my current to replace it and build my own to replace my current. I'm not very experienced in this kind of thing but I've got my base hardware down. I'll be getting an Intel i7-875k Processor along with an Intel DP55KG Motherboard. Where do I go from here and what do you recommend I get?
