I do a lot of work with Qnap’s TS-431 rackmount series atm (building dedicated docker machines) and they’re pretty sweet noise-wise. I can actually hear if a drive platter is dodgy over the system db. Something to consider?
If I can find a good, cheap 4 bay nas that would be just as good. But I can’t seem to justify to myself to pay $200-$300 for a four bay nas when I can pay the same amount for other options that either have more storage or more compute. Don’t have much room or money, so most of my lab wears many hats, and I like to purchase tech that can fill as many holes as possible.
