I am running a tuxedo since 6 years and I am still happy with it. Had to use their support once to replace the cooling assembly because one of the fan bearings started to ger noisy after 5 years of 24/7 use, the replacement was 100 Euros for the whole copper+heatpipe+two fan assembly. The machine is still outperforming many other machines that exist today and the sceeen is one of the best I have seen (OLED).

Software side was smooth sailing as well.
