Bought, yes. Buy, not so much.

Because where will you buy the replacement once RPI plc has discontinued it? Esp. considering the likes of https://www.cvedetails.com/vulnerability-list/vendor_id-1973...

Not that different for the prodesk/elitedesk small form factors IMHO. There’s a steady supply of cheap used ones available on most online marketplaces (there’s probably millions of them being cycled out of offices every year).

Get a new replacement one, swap over the NVME. Doesn’t have to be the same cpu, linux handles the rest.
