I've been tempted to modify the Wiki for the Express assembly manual myself as it does have some issues, such as the order of installing stuff (it's supposed to be lower items first, but the instructions tell you to do things like install the voltage regulators with the big heat sink before the tiny little headers that like to fall out), and some of the resistors don't have the colors specified.
And I'm also confused about the 120 ohm resistor. The instructions say that it's Brown, Red, Brown, Black; to me it looks like Brown, Red, Black, Black, Brown. I had an ohm meter to check before soldering my first one, so it wasn't an issue, but I imagine that it can cause confusion.
