A very good post @jrswab !
Thanks for this one. I used to have a linux server (with GUI / desktop) and was always a fan of Linux - especially Ubuntu. Still, I used Windows-based systems parallel. I never changed all systems to Linux.
Last year the hardware of my little Linux server died and right now I'm looking around if I can get some nice hardware again to build a new one that is not too expensive. Actually, I'm looking for a second hand / used one.
If possible with enough power to become a witness - that would be perfect.
But until now I did not find the right one that fits my budget.

Thanks for the post which motivated me again to look around even more for what I can find.
