I'm looking for a Thunderbolt 3 DAS with at least 8 SATA drive bays. I came across OWC's ThunderBay 8 which seems to provide what I need, although there aren't many reviews. Do you have any opinion on this DAS? Would it be cheaper to build something like that from scratch? I'm not looking for a NAS solution but DAS over Thunderbolt 3. I'd prefer to build the unit myself but don't know where to begin.
