I'm very impressed with my N100 mini PC (fits in your palm) that I bought from AliExpress. Takes between 2-8W and uses just a plain old 12V plug-style power supply with a DC barrel. Perfect for Home Assistant and light virtualisation. Performance is actually better than my quad core i5-6500 mini PC. Definitely no slouch.
