Good.
It's a change from the tower! Completed with a 500GB M.2 ssd (max limit according to ASUS) and 16GB of DDR4 3200 MHz memory.
Installed LMDE 5; I immediately noticed CPU T° levels around 90°C when well used (update after install + large file copy + browsing) and still around 60-70°C in average use. All this was fixed after the BIOS update (->0409); now the fan very seldom goes crazy but it continuously makes a low noise at a frequency I don't like too much, maybe due to the BIOS "CPU FAN CONTROL" setting in performance mode. Otherwise, it seems to be a good (very) little beast. I chose ASUS for its recognized reliability (by others!)
