Looking for a Christmas present for the geek who has everything? How about this - a detailed 1:18 scale model of the Delorean from the Back to the Future movies, which is also a 500GB hard drive? The $250 cars-shaped hard drive features gull wing doors an opening bonnet and even a replica of the reactor needed for time travel. It simply plugs into your PC's USB socket and you can utilise the Seagate storage hidden within. Dave Hersch of US company Flash Rods says: "After four years of engineering, it's finally out and worth the wait. This is one of the coolest hard drive cars we have ever made. It would be hard to have more fun than this rolling around your desk top."
