Fair enough. I mean for me the equation might be a bit different, I’d pay about 200€ a year in electricity to run 3 efficient computers. And my VPS is only 73€ and I never have to pay for replacement parts (SSDs, harddisks) which I had to replace at home and they have gigabit network, a proper IP address and that’s all way better than what I have at home. So it’s a no-brainer to go for that. But your cost calculation might be different.
