@skylark13 @homelab Well, before I set up the PC I had been using one of these:

Unfortunately after about three years the SSD died, and it's all soldered to one board so there's nothing you can really do but throw it all out. I did calculate the difference in power and what that would cost, and for me it would have taken about five years for the power savings of that box to make it cheaper than the PC overall. So depends on your local electricity prices, but for me trying to save power would have been a waste of money lol

But yes wifi is a potential issue. An old laptop wifi card in the PC worked fine in a two bedroom apartment, but when I needed to have it in the basement of a three bedroom house I did have to add a dedicated AP.
