Quote from jonathan55:
This is a difficult project. It is imperative that you read the entire guide before you proceed. Have a system in place to keep track of the screws so you know what goes where. Budget several hours for this.
Nonsense! Even a non-technical person could follow this guide and do the job in 15 minutes. Anyone who's done any work on any kind of computer will be able to do this in 5-10 minutes.
