Mac2geezer- I agree that the plastic on the original iMac series is not durable at all. However, if Apple had made the plastic any thicker, the convection system probably would not have worked (revenge of the 3 original Macs; goddamn you Steve Jobs!). Even with the materials used, my G3 heats up pretty quickly, sometimes to the point where the carrying handle becomes unbearable to touch (and I have adequate ventilation in my room).

Do you have any case cracks on your G3? The reason why I am posting this on the forum is because the housing on the top case on the right-hand side of the iMac (its right, not mine) has sunk a bit, in comparison to the left-hand side, which does not have this crack. Again, my question is: should I be concerned about this, or should I just leave this be?
