It was not clear to me from reading this forum how easy or hard it might be to install Ubuntu on the NEO Z83-4. I decided to get one anyway and try it. I followed the instructions at http://linuxiumcomau.blogspot.com/2017/03/running-ubuntu-with-upstream-kernel-on.html to "respin" the stock Ubuntu 17.04 iso image (I guess needed for the 32-bit UEFI bootloader?) before writing it to a bootable USB stick. Then I was able to insert the new USB stick, turn on the Z83-4 and immediately hit DEL to enter the BIOS setup screen, change to boot first from USB, restart and install Ubuntu normally (wiping out Windows 10). I also changed the BIOS setup parameter to start at poweron instead of waiting for the pushbutton. The result is that Ubuntu 17.04 does work. Cool. Right now it's compiling a program using all four cores and only drawing 6.5 watts at the AC wallplug, so it it is also literally cool, or at most slightly warm (case temp is 33 C, ambient is 23 C). When I connect an external 4TB USB-powered drive and have all cores working at 100% (analysing video streams, and sometimes recording) the average draw is 7.5 W, occasional peaks to 10 W. I don't think wifi or sound works unless you do some additional steps, but I'm not using wifi or sound anyway.
