I’m not sure why the author brought up used Apple TVs without even mentioning Mac minis. The 2012 Mac mini has two 2.5” drive slots, replaceable RAM, a quad-core processor, low idle power consumption, it’s quiet, and you can upgrade it to the latest macOS with OpenCore Legacy patcher. The cost is around $100. Chrome Remote Desktop and Jump Desktop are two good ways to access the GUI over the network, or of course you can use SSH or install Linux if you’d like. It’s probably not the most cost/performance efficient option but if you have any need to run macOS it’s a good choice.
