There's a parallel worldline out there where the PDP-11 made the transition into a desktop PC[0] and the IBM PC didn't take over the world. In that worldline our servers are from the PDP-11 lineage, and not the IBM PC.
I've got a DEC Pro 380 myself ( https://oldvcr.blogspot.com/2025/03/more-pro-for-dec-profess... ). It's a heck of a desktop computer, and you can run some early Unices on them. The Pro and the DECmate II are some of the best built systems of the era despite their idiosyncrasies, IMHO.
