Yes. I have 3 "servers" that are all just Ubuntu server running on 3 laptops with lots of storage and RAM 🥹

Boy do I have (another) space heater for you if you want it :)
I used to have fack mounted servers and a rack and ups and rack mounted switch 🥹 This was many, many years ago. I've scaled down a lot.
It happens. I still have this equipment although I upgraded and was able to downsize physically, but an upgrade in performance! This rack was fun and cheap, I knew a guy in government auctions. Most of that equipment came from Alphabet agencies.
Ill have to list some of this old stuff soon. I think we are "fairly" close to each other if you know anyone that is interested :) I'd like to see it back in action.
