NAS hardware shopping

Hi, a somewhat off-topic question.

I’m looking to build or buy a simple-ish LAN-only NAS, probably running TrueNAS. The parts research and shopping has been exhausting so I’m leaning now toward purchasing a mostly pre-built system. I’d prefer to support a privacy/security/freedom-aligned vendor.

I’ve looked through the offerings of a few vendors that sell Qubes-certified hardware but none seem to be quite in this market. (To clarify: I’m not looking for Qubes-certified hardware specifically, rather vendors who nod to the ideals of projects like Qubes and offer a home storage product line.)

Does the community have any suggestions? Or maybe a pointer to another resource where I might find answers?
