Used mssql-server at work where we usually use windows and its a bit shit if you want low memory hosting. Though when I have run MySQL I haven’t tested low resource systems to compare that either tbh.

Can’t you run Apache on pretty old hardware? I thought it was something you could happily run on even some of the older versions of raspberry pi. Probably depends on what you are hosting on it of course.

Kinda want a low lower draw device to use as a server, ideally proxmox and just backup the whole VM image once its setup. But not sure how much I would really use. Very basic Apache/php, pihole, not sure if there is too much else.

Maybe factorio servers if I get into clusterIO stuff again.
