I got the HP ProBook 450 G5 Notebook-PC on Ubuntu, it's decent, sd card reader and fingerprint reader not working for now (but i dont use it much). The graphics are trash for any form of gaming/video work, but it's not getting hot like my previous hp with an nvidia GPU. One really neat trick is that you can do a 3 screens setup very easily by connecting one screen on VGA and the other on HDMI, without any dongle.
