Want on prem. Corp grade screwless entry PCs now look pretty good as generic home store devices. TrueNAS and zfs, she's good. I went wierder, card from here, secondhand PSU from a market in bangkok, random SSD, cables, a zimaboard.. 3D printed parts. Great fun. Unmaintainable.
In modern environments most equipment is often already treated as ephemeral. There are few major upgrades in maintenance cycles, but rather the whole rack is replaced periodically... and the data store repairs the distributed volume. =3
