OWC Ministack 0TB HDD Enclosure. Comes boxed with a USB-B to USB-C cable.

It has a Mac Mini design (so you can stack them - looks really cool when you have a few and a Mac Mini) but can be used with any machine.

This item was bought new last year and I was going to set up a NAS on a Mac Mini that would connect to the DAS but never got around to setting it up. I somehow managed to scratch the upper plastic which I've tried to show in the photos. In great condition otherwise.
