Today i finally jumped it and threw my money at an Asus Zenbook UM431 with a Ryzen5 (Good bye, Intel - i hope i won't miss u).
Mainly because of the slightly bigger dimensions than the newer UM433 models and the better bottom vent placement.
At about $600 without windoze, it's OK for me, but that's still some fiat i didn't invest into corn, on the other hand.
