I have been working on this mod or derivations of it involving the iMac G4 on and off for a year. Although, I am happy with the result. I have left a sea of burned out lcd controllers, inverters, damaged lcd screens, and parts from broken iMacs in my wake. With the money I have spent on this mod I could have probably purchased a working 20 inch iMac G4, upgraded it to its max, and be halfway towards the purchase of a brand new 27" iMac. I would be lying if I didn't admit that I think about 65 solder joints (most on 30 gauge wire) being pulled every time I move the neck. While I am certainly no electronics expert, I have been modding and working with computers for many years, these LCD screens, backlights, and controllers are the hardest things I have ever worked with. They are so sensitive, so easily damaged, and sometimes they do strange things. So while I would never discourage anyone from doing this project, just know what you're getting into
This has made me come to appreciate the original machines so much more. The fact that apple was able to fit a computer, full drive, hard drive, power source, amp, speaker, and graphics card in the base is incredible. The fact that even years later it is so hard to improve upon this computer demonstrates how great their design is.
