I know its been a long time, but after multiple shipping snafus i finally got everything i needed to do the PCB. It works perfectly. Multiple CCFL output issue is resolved. Mechanical adaptation requires some modification but i dont think it is beyond your average DIY person's ability. EDID info is stored on 24c02 chip on PCB so no need to remove from screen. No soldering necessary with this PCB.
I am going to use this iMac on a daily basis for a little while but based on the past 12 hours i dont foresee any issues.
If anyone is interested i can produce more PCB and sell them pretty much at my production cost. i can also make an instructional document for recommended installation procedure.
