Good to know. After that answer I am know 100% that you are an expert. Maybe post your CV afterwards, "honey"

Actually I run both rpi4, zeros, optiplex and home made servers. But do your own tests. Make sure you document them and send them to me to prove that your correct, because by your logic, with no proof, you look like the bias one having a rant on a dam hobby ;)

Thank you, didn't notice.

Yes, i did. But take it as you want. Just an opinion.

There's plenty of stuff that maybe I don't want to self host on the same device and that I would rather host on RPI due to power consumption for example. Not all about money and recycling old computers, but regarding ecology also spending less energy it's extremely important. Imagine a full desktop computer just to host pihole + pivpn. Sorry but your statement is pretty bias.

Just follow guides on turn it off "crap" that you don't want.
