With the BIOS update I had no issues loading and running Ubuntu 16.04. No drama, no fuss.Quiet performance in my environment, though I am not pushing it that hard yet. Attached three Seagate 4TB portable drives via the NUC's USB3 ports, and three more 4TB Seagate disks that are connected into a Unitek Thunderbolt 3 disk dock / hub to the NUC's Thunderbolt 3 port. Surprisingly enough to me is that the little NUC could drive all six disks with no additional power feeds.  Nice.FWIW, I use this disk setup for rsync backups of a Synology diskstation (using LVM disk sets) -- one set permanently connected, the second for off-site backup storage. Cheap and good.
