Did this bc there were no Pis to buy a year ago and I’m really glad. Learning Proxmox and hosting a ton of stuff on a little thin client the size of a VHS tape that was about 200€ and sits quietly in the corner of my room was totally worth it. There are alot of offers for used ones on ebay, e.g. lenovo thinkcentre mini, hp prodesk mini, dell optiplex mini.
