Hello so im thinking about getting a disk shelf this would be my first time getting one and setting one up. So my question is. 1: what exactly is a disk shelf? 2: how do you set one up? If you could explain or send me to a good videos that explains both that would be really appreciated. Thank you for your time and have a wonderful day. Sent from my moto g(6) (XT1925DL) using Tapatalk
