Hi, I just acquired a PowerMac G4 500mhz that works great. However, the hinge is broken. It is on the right side (if you are sitting at the laptop). The screen casing is broken where the hinge is. There is nothing wrong with the screen, just the aluminum cases that covers it on the edges. I was able to remove the broken hinge from the computer. My problem is attaching a new hinge to the case without damaging anything. Can anyone give me any suggestions? Thanks.
