    Almost sad the newest buy, an iMac G4 15" is fully equipped (2 GB RAM, and sufficient disk space) so I have nothing to upgrade. (Maybe an overclocking to 1,25 GHz later.

    Remains cleaning and minor maintenance:
    1. The upper articulation (behind the flat panel) of the arm is a bit loose, the screen does not stay vertically. Do I need some special tool for the 3 holes on it?
    2. The screen itself has some light scratches. Can I replace the foil with one from a nonworking 15" laptopo?

    A picture of it. The upper articulation is the one I would like to know how to tighten.

    If you look for iMac G4 neck adjustment kits - you may find what I found, that the kits, with special tool have been discontinued for years.
    I did find this forum thread, not too old (from 2012), and may be helpful to you.
    Appears that the adjustment doesn't need a lot of torque, so you _might_ tighten using some sharp-pointed needle nose pliers, or something similar. Those hinges do wear out, so I don't know how effective a simple adjustment will be for you.

    go to an auto parts supply place and get a set of feeler gauges. use some scissors to make yourself a shim and stick it in the right place. try a few feeler strips to find the correct thickness.
