Here is a 1:18 stainless steel DeLorean from Back to the Future that serves as a 2TB hard drive. As Sedona Studio explains, the car is highly detailed with gull wing doors and hood that open. These Flash Rods cars are designed to completely hide your hard drive and can be powered by your computer. You can use them with Windows and Mac computers.
Only a couple of these are available for purchase. You can order yours on Etsy.
