For those interested in learning more about the metal under their PC's hood, Tom's Hardware has a great intro to PCB manufacturing, Ars Technica has recently written an architectural study of the P4, and ExtremeTech has a decent look at the South Bridge." The circuit board article is really good - explains it better than the textbooks I've seen.
