I am training a client's 14-year old son to be able to take apart equipment he can deem to be qualified to do. To this end, he is being provisioned with the tools needed for computer and other small electronics projects.
This young man replaced the hard drive on my 2009 MacBook Pro with a new SSD very handily. He noted that it is easy to learn how to do something with the "right tool for the job" equation.
Some Tips From The Pros would be nice for beginners.... along with the videos, there might be a section for some-one just entering the field.
