I currently have this (and don't want them to collect any dust: Asus Motherboard Quad Processor DDR Memory Plus a couple hard drives, but absolutely nothing else. Since this is new to me, I'm asking: 1 - Is there a way the more experienced users would suggest going about a new case and how to know the appropriate power supply to buy. 2 - I bought the MB used from newegg.com, and it didn't come with any wires/connectors. Can you tell me what I'd need to fully be ready when I have all the components? Thanks!
