Albert, I don't know if you've solved this problem yet. I am wondering - do you mean the part that connects to the LCD at the top or the part that connects to the motherboard at the bottom? The part at the top is a standard 30 pin LCD JAE connector. If you go to ebay and search for LVDS cable, you will find several cables that have the same 30 pin connector that you can use. The bottom that connects to the motherboard is also a type of JAE - but female connector. You can buy the receptacle from online suppliers such as mouser or digikey, the name of the receptive is: 656-FI-WE21P-HFE However its tiny and difficult to work with. Worst case scenario you could always buy a replacement neck on ebay.

You won't come close to the specs of a MacBook pro, but you can build a respectable core 2 duo machine with similar specs to the current generation Mac minis. I have just completed my iMac g4 20" all in one mod by using the LCD controller board and wiring from a 20" apple cinema display and an ECX form factor motherboard with a 2.53 ghz p8700 core 2 duo processor. The cost of the "computer" including board, ram, fan, CPU etc was around $600 total. This includes the 32gb compact flash card that I'm using as a HD. The power bricks are external (because of space and heat issues). If you already have the iMac g4 chassis you don have to worry about this but a non-working 20" iMac g4 with a likely working screen can probably be purchased on eBay or around $100. Then I'd look for a cinema display with a cracked screen or faulty inverter (if the iMacs LCD is broken, the apple cinema display LCD can replace it). I got my cinema display for around $60 with a faulty inverter. Even adding in cables, supplies, blu ray...
