Now running Proxmox with some Minecraft servers, several programming projects, telegram bots, VMs for friends, android building, storage and similiar.
Consuming around 300W in average load (this is Italy, and I pay around 0.29€/kwh), most of the hardware comes for free decommissioned from businessess, or for cheap from charity shops. I exchanged my old Intel Core 3rd gen machines because they only had 2 slots of DDR3 non-ECC RAM and I needed at least 32GB per machine.

This is a small closet room inside my bedroom. You can't really hear the sound from outside, so I set the fans to max power. It's less than 1.5 meters tall, so it's really hard working inside. Everything that can be done remotely is done remotely.
I have a symmetrical 1G/1G fiber connection (29.99€/mo)
I discovered them recently. In the one where I go most of the time all the people there are volunteers, they have agreements with local landfills to take good things and resell them where the profits go to a charity that helps poor people in Latin America.
I'm sorry for the connection price lmao, here you pay always around 20-30 euro a month and you get the best connection that you're covered with, so 1G fiber, 100/200M FTTC or ADSL. You can also get 2.5/1G and 5G/700M fiber in some cases for around the same. Only a few ISPs offer 10G/2.5G fiber in limited areas and for a higher price.
