Replacing motherboard for iMacG5: it is getting difficult...

Yesterday, we were reporting a 2 to 3 weeks delay for having a iMacG5 motherboard replaced under AppleCare conditions.
Myriam has obtained information regarding the reason behind such a delay!
Following the well known, reported and described problem affecting the graphic card of her iMacG5 (November 2004 production serie), she has received a motherboard from AppleCare on the basis of the "Do It yourself" program. After one and a half hour of work, she realized that the new motherboard was simply defect too!! Annoyed, and after bringing her iMacG5 to an AppleCenter, she has learned that it was the 96th cases of defective iMacG5 replacement motherboard that Apple has sent to Europe!!
This is probably the reason why currently it is impossible to obtain a new motherboard. All stocks have been sent back and all AppleCenters are waiting for new ones to be delivered.
