Mount iSight to iMac G4 without adhesive

I've been looking at getting an iSight but haven't figured out how to mount it to my 15" iMac G4. My sister got one and the only mount that came with hers that i might be able to use is the adhesive one which i don't want to use. The mount that she used to clamp it to her screen didn't work on my iMac. I would like to find a mount that would attach to the plastic edge around the screen and am not sure if the accesory kits comes with one. Hope you can answer my questions.
