Here’s a little known fact that most people have no clue about: Back in the day, when Apple was working on a new computer model, the prototypes before mass production would feature clear, translucent casing. Don’t believe me? Fire up that DVD player and go watch Hackers. Angelina Jolie uses a clear-plastic Powerbook in the movie. And this Mac SE/30? No exception. It’s a beautiful-looking pre-production model that any collector would love to own.
