I have Mint on the 2014 Mac mini I use as a media and Home Assistant server. It was my first dabble with Linux, and I now wish it used Plasma instead of Cinnamon. My other Linux machines are running Kubuntu with Plasma, and they're great, so logging into Cinnamon always feels like a step backwards somehow.
I could try changing the DE on it, but I'm not massively proficient, and don't want to have to set everything back up again if I fuck it up.
