I wanted to resell my MacBook rather than throw it in the garbage. The problem was the broken keyboard cable. So for $33 dollars and 30 minutes of my time I have a working MacBook that I can sell back to Apple for $221. Net gain of $188. Just enough to reinvest in a new iPod nano.
Much easier than it looked from the photos.
Your old Mac is worth money. Fix it so someone else can use it.
to see how much you can get.
