I bought this as a test replacement for a failing RPi 3+ that I was using for Home Assistant and a few other self-hosted apps. Since it's been hard to find a Pi here lately, and this refurbished small form factor PC had much better specs than even the best available Pi 5, I took this route. This is also more affordable than decking out a Pi with everything you'd need to actually get it up and running. I'd be hard pressed to determine if this uses less power than a Pi, but I can also run a lot more apps on this than a Pi.The form factor was a bit larger than I expected, but I got over that real quick. It's currently hidden back where I don't see it anyway.
