Yes, and you might want to ask in the datahoarders community.
While I dont use a mini-pc, I have a server with 48TB in it on spinning disks, and I've built a hybrid DAS/NAS that I back up to.
I use this 4-bay DAS: https://www.amazon.com/gp/aw/d/B078YQHWYW I chose it because it supports USB 3.2 Gen 2 and I've been pretty happy with it.
It's usually plugged into my server directly, and I use ZFS to snapshot and send to it. However, I also can plug it into a Pi5 and use ZFS send over SSH to treat it like a NAS. The Pi can of course run Samba/CIFS and SSH for sshfs.
The biggest downside to this structure is probably the metadata speeds for ZFS over USB (looking up snapshot names), but you could always use a cache drive with ZFS.
I highly, highly recommend ZFS and figuring out your software requirements before picking hardware.
Happy to answer any specific questions, too.
Have you had data loss occurences in these bay enclosures? Some other commenters have said, that using it as a primary storage is really risky because some crappy controllers could ruin the drives's data for example.
Yes there is someone talking everybody down about USB enclosures*.
Maybe he got burned or something...
Can say never had an issue and I replaced many motherboards over 20 years, and also many enclosures.
Don't go too cheap, but don't worry too much. I highly recommend a raid setup anyway. And always do backups, bit this is unrelated to USB specifically
