The first half deals with hardware selection and even esoteric concepts such as PCI slot placement. The second half is focused on Windows XP, and makes recommendations such as moving the swap file and scratch disk to a separate partition." From the article: "You laugh at the so-called expertise of Best Buy's GeekSquad, and are the one doing the teaching when calling technical support. If this sounds like you, you've come to the right place if you're looking to take your system building skills to the next level."
