I have ZBOX MI571 with an i7-6700T and 16GB (SODIMM) RAM laying unused. And I want to make a personal backup/archive server, for which I think TrueNas will work best....
I’d start over. A mobo, decent CPU, lots of ram for ZFS, and a used LSI storage adapter from eBay would get you far on a budget. USB won’t have the performance or reliability and you’d need a handful of drives to make it worth it. You could install an M2 SATA adapter, I don’t know if it would even work, and drive drives with it but they would still need power and you couldn’t put the case back together without cutting holes in it.
Possibilities to adapt ZBOX into TrueNas server
