Hmm, I might just see if I can use a q-tip on it and see if that works. I really don't want to take the case plastics off because of what happened when I put a DVD burner in my family's Dell. One of the plastic tabs on the front panel snapped and now I have to put tape to hold the front of the case together. The only upgrade I will be doing with it for a while would be upgrading the RAM and re-installing Mac OS 9.I haven't taken one apart in a while, but if I remember correctly, you have to take the shell off before the front plastics will come off.
It will sound like it is breaking when you take it apart too, but it really isn't.
I have a question, I want to know if I could go out and buy a USB to serial (With the 9 pin plug) and put my PC to Mac serial cable in there and transfer stuff from my PowerBook 150 to the iMac.
