While everyone is transitioning to lighter and thinner laptops, you can show your love for Apple's venerable—and occasionally updated—Mac Pro tower with this custom printed 3D iPhone case.

If you're lacking a 3D printer at home, and the 3D modeling skills necessary to create your own, you can just order this case from Shapeways for just over $30 in your choice of color and materials. But for authenticity we recommend going with something that matches the Mac Pro's lovely brushed aluminum finish.
