Klantenservice: Serienummers will check your serial number for qualification to a number of these programs:
[Harald van Arkel] We updated our serial number analyzer. It is now aware of the iMac G5 Exchange Program. If you enter the serial number of an iMac, it will warn you that it is part of an Exchange Program. The analyser takes the serial number of any Mac (or other piece of Apple hardware) and tells you what exact model it is and when it was produced.
