Are you looking at the serial number information on this site? If so, THAT IS NOT AN OFFICIAL APPLE SITE - it's run by random people not affiliated with Apple. Why would you take the information this site presents as the final word on the specs of your machine?
My bad, I know it's not an offical site however I thought this is the place most people here have been using for reference. The rest of the info stated is correct but it did seem suspect when I saw the PATA info. Thanks to everyone's help for clearing this up.
