Resumo: I'm using this with a recommended linux distro - RHEL 7.6
All I can say is I've had nothing but pain. it will not work out of the box. I've had to resort to producing ansible automation just to automate installation in a reliable manner, because even a yum update might break the config.
Resumo: What a magnificent machine! HP did their job. This machine PERFORMS and makes no sound in doing so. Love the Z Turbo SSD. Backups which use to take minutes to do now are done in a blip of a second.
