Just empty your mind at the moment – how much space is 70TB? Before you go wild with your imagination (or just are plain terrible at math), let us list down the nitty gritty. On average, 70TB of storage space is able to hold around 24 million songs, or 70,000 movies at DVD quality. This is what you get with this DIY home computer, where it holds 60 hard drives for a grand total of 70TB of storage space, all crammed into a wood cabinet. Good thing there are 40 fans inside that prevents it from catching fire. Yowza!
