Don't know of any guides but generally stuff errant cables A)behind the mobo, B)behind the mobo tray or a combination thereof. You may need to cut holes in the mobo tray to feed through next to ports. Also you may end up needing longer cables depending on how out of the way your components are. To make things look extra tidy wrap as many cables in cable braid as you see fit, depending on how pernikity you are. Its not rocket science.
