I’ve seen several people move to an Intel nuc, but felt the price / performance to be a little high.
i settled on a gigabyte 4105
8 gb crucial ddr4 mem
512 GB m.2 ssd
Total cost $261 (at the time of my purchase)
running hass (HA not hass.io) on a vanilla debian 9 install, with node-red for automation, mysql for the db and grafana for dashboards
big upgrade from my rpi3
anyway, putting the info out there in case anyone was looking to move to a nuc… here is an alternative way to go that i can recommend.
