Hardware pictures
It's a small gpu with a small, yet loud fan.
Installation steps
MacOSX:
Booting with @goalgque EFI-Loader that eGPU is immediately recognied by the system:
Unfortunately without the correct driver the external display stayed black. It's not possible to install the on High Sierra:
which means, there was no way to get it running on MacOSX.
Windows:
Typically for nVidia cards the Windows installation can be successfull. Just boot into Bootcamp, hotplug the eGPU during the loading and find "Microsoft Display Adapter" under Device Manager. Install the correct nVidia drivers, reboot and everything is working fine:
After the installation of the driver the hotplugging is only necessary if you want to have your internal display with the Radeon Pro 560X working.

The middle column contains the benchmarks of a kind of "collaboration" between the dGPU and eGPU. For Heaven and Tombraider this means streaming the pictures though the eGPU onto the external monitor. For Luxmark, it's a classic combining.
Comments
I am planning to elaborate more, only brief for now: This is a test if the system works with low performance gpus, too and how it behaves. There have been some very interesting aspects, e.g. it's possible to accelerate
- from dGPU to the external monitor through the eGPU
This is exactly vice versa than to accelerate
- from eGOU to the internal monitor though the dGPU/iGPU.
