Greetings, its the noob again:) Recently I had a discussion with a friend of mine who claimed that he knew how to set up his own computer (putting the parts together, not making the parts themselves). When I asked him if he's ever done it, he said no, but he said that he knows what most of the parts are and that if he had the tools he could figure it out. He knows absolutely nothing about electrical circuits (or electricity for that matter) because he's never studied it. And when I asked him if he knew about grounding, his reply was: "what's that?" So I'm wondering, is it really possible to set up your own computer with the limited knowledge that I described here, or are there very important things that must be learned first? If so, what are they?
