I only just saw this completed build. I am glad I could have helped with the jumper.

Yikes, that is one crazy solution to fit the add-in card.

Can both the Thunderbolt 3 ports be accessed? Or is only one drilled through?

This is pretty cool, especially that it is AMD. What I wanted to see from Intel NUCs was for them to be able to be powered from Thunderbolt ports, in which case we could discard the power pack and power them at 100W from the Aorus eGPU. In theory you could find a way to fit the NUC motherboard inside of the eGPU. If you use R9 Nano, there is space above and behind the GPU. Not quite enough, but you could mod the Aorus case to allow the motherboard to protrude a little. That would make the Aorus eGPU its own computer with USB ports and the Thunderbolt cable at the back. Then the NUC inside could be powered down and the Thunderbolt cable attached to a laptop. Which would make it very versatile.

I am hoping that eventually the makers of eGPUs will start to make the mounting holes compatible with ATX cases, so that modders can take the PCB out of them and place it in any standard PC case.

On a tangent:

I hope that one day Thunderbolt can allow a laptop to borrow the GPU of a desktop (access in the same way that a virtual machine would access graphics). I believe that theoretically, Thunderbolt can do that - but it will require firmware changes and improvements to make sure all consumer / mainstream platforms have their IOMMU and SR-IOV (or potentially even MR-IOV) working.

I am different to other people in that I will take absolutely any opportunity to use the same hardware I own in other ways. Many people will say "gimmick" or "nobody really wants that" but if everything is there to enable something, and it is not enabled, it frustrates me. I believe that PCIe and DisplayPort should be fused - the benefit is that every computer can then be a high performance capture device without any additional hardware, and that any laptop will be able to be used as a portable monitor. There are dozens of cool things that would benefit people, that nobody has really contemplated. People might say it is a gimmick. But if you actually deliver it, they might start to try it and go "well actually, this is useful".
