Sure you can buy an external hard drive enclosure for pennies but it wouldn’t have a glowing Apple 
logo on it. And let’s be honest Apple users tend to care about how their gadgets look. They have some of the prettiest desks and accoutrements.
I am not sure how long this listing will last because I am sure Apple didn’t authorize the use of their trademarked Apple logo on this slick 2.5-inch enclosure. Buy them while you can here ($26).
