I use Linux mint, Mac OS and W10 depending on what I am doing
I'm running it on a Dell 7040 Micro tower. I've configured LXD containers to run services, and Docker containers for various "tool" purposes (such as Kali, AWS CLI and Hugo). I've also got a Dell 7060 Micro running Proxmox, although I've not yet gotten too far into that. I intend to use that, plus Zero Tier, to extend my Evil Empire around the globe. :)
I begrudgingly have to run MacOS during the normal workday.
