[Build Help] Found a few parts, how can I make them mesh?

Build Help

Hey BaPC, I was cleaning out a storage space and happened upon a few components that I forgot I had. Those are the items in the list below that don't have pricing data. If I bought the rest of those parts, what else would I need to get things working? I'd be using it mostly for gaming, making music, and watching movies. Advice is appreciated!
