Your model number doesn't match, but maybe it's just the model number for the case alone or something. You can double check that at this page: http://docs.info.apple.com/article.html?artnum=58418 and you can also go to this page and type your serial number into the second box on the right side of the page: http://support.apple.com/specs/ I used to work with a John Heald in Littleton, MA. You're not the same John Heald, are you? -- Rich
