There's also lot you can do with not-brand-new server hardware that doesn't cost that much. The hard part is a location to put it where the noise is not bothersome. Though many who are "upper middle class" or on low-cost private land can manage to make this happen. I have seen people that don't have a lot of money, rather young people, do a lot on private land. Small dedicated server buildings are a thing.
