TechReport: "So, you want to build a PC. The process is a lot easier than you might expect, even if you've never pieced together all the components that make up a typical system. Although the underlying technologies are often stupendously complex, modern PCs are no more complicated to assemble than the average piece of Ikea furniture.
Well, that might be a bit of an oversimplification—but only just. Today's PC hardware is definitely user friendly. All of the various parts are designed to fit into only the right sockets, slots, and ports. In most cases, installation requires little more than a screwdriver, if that. Newer enclosures and power supplies have also smoothed out the wiring process considerably."
