Hey guys, here is the idea. I want to put the Thuner2 eGPU PCB into my mini-ITX PC. So I could utilize the SFX PSU and GTX 1060 in my PC when the PC is turned off. Maybe that also need to do some mod on PSU.

If there exist such PCI-E riser with 2 input sources, one from PC motherboard and another from Thuner2 PCB. The output will go to my Graphics card. And there is a hardware switch I can switch between them. Then this idea could be fulfilled.

When my PC is turned off. I could simply plug my MacBook Pro to my PC and turn the switch to Thunder2.
