Database of all Mac models

Try MacTracker. It's available in the App Store and Mac App Store. I hit enter before I finished thinking through my answer. What info do you need, Model Numbers or Model Names?

Over at apple-history.com you can download the html of their Mactracker-like information. Probably wouldn't too terribly difficult to scrape your info from it. Below is an example of the html you can download from them...
