Yeah, I just use plain boring desktop hardware. (Oh no! I’m experiencing data corruption due to the lack of ECC!) It’s cheap, it’s available, it’s trivial to upgrade and expand, and there’s very few little gotchas in there: you get pretty much exactly what it looks like you get.

Also nice is that that you can have a Ship of Theseus NAS by upgrading what needs upgrading as you go along and aren’t tied into entire platform swaps unless it makes sense - my last big rebuild was 3 years ago, but this is basically a 10 year old NAS at this point.
