Everybody has to start somewhere. I didn't have a clue about building computers, until I built my own, which is the one I'm still using right now. I learned from taking advice from people on here, and by reading tutorials in magazines, and on the Internet. It's actually not that difficult to learn where the main components all go, and not difficult to fit them together, as long as you are patient, and willing to learn, sometimes from your own mistakes. The main thing to remember is that some of the components are quite delicate, and are not made to be treated like sticklebricks. They can also be expensive, and it could, for example, cost you a £60 CPU by simply dropping it and bending a pin, or not fitting the heatsink carefully enough. Be prepared, be focussed, be careful, and you'll have made yourself something to be proud of.
