This was a very clear and helpful guide. Thanks, Andrew!

One point that I thought would help others trying this for the first time is about the mechanism holding the RAM. As the guide points out, the RAM chips should 'pop' up when the clips holding them down are properly extended to the side. And when installing the new chips I found that though the force applied was between light and moderate, relative there wasn't much force needed to insert them into the board as there was to push them downwards until you here a 'pop.' The force needed to be applied at any stage of the whole process was minimum to midway between minimum and moderate.
