It's amazing realizing that I posted this almost 2 years ago. This is no longer how I would approach this mod at all - in fact I disassembled this particular mod as a result of safety concerns. For the 20" iMac mod you can use the native, unaltered frame, LCD, and inverter. You need to alter some of the wires in the neck, but it is compatible with the controller board from the aluminum 20" apple cinema display. Thus, you can turn your iMac into an external monitor or a modernized all-in-one. But, the conversion to LVDS is no longer something I can recommend doing.
The iMac G4 forever changed the way I viewed computers. With some modification it can be used as an external monitor or updated all-in-one computer.
