Do It Yourself, intermediate level

Apple has published a few tutorials on how to replace iMac G5 parts by yourself(20" and 17").
For all replacements, the difficulty level is said to be "intermediate". This word not meaning a lot when it's all by itself, Apple is not taking any risks.
We ran by a few of those PDFs. The instructions are clear and simple. All of them are accessible to anybody not afraid to use a screw driver. Quite frankly, if we had to rate them, we'd say they are very beginner friendly, except perhaps the ones for midplane assembly/disassembly which are a bit short.
