With my recently bought computer, i realized that there was a color code for hooking up the wires. This takes all of the fun out of putting it together. Any moron (well, almost any moron) can now successfully hook together a computer. The code (for Dell at least, but it seems to be an industry standard sort of thing) is as follows:

Blue: monitor
Green: mouse
Purple: keyboard
Light Green: speakers
Red: microphone (or other comparable device)
Black: power supply

This is part of the PC99 program, whose participants include Intel, MS, and pretty much everyone else. The first products that started showing up with color coding came out in the late 90's as companies decided that it was a marketing point, and larger companies (DELL and others) started demanding it of their suppliers. Intel has a whole section of their website dedicated to this.
