It would be cool to make an eGpu with a docking station, like the ROG XG Mobile and GPD G1. They both have significant drawbacks, the ROG XG Mobile connects via a proprietary port, and the GPD G1 has low power for PD. For the docking station, you can use the standard infrastructure, the GPU board that you already have, and expansion cards, so you can assemble a docking station for yourself with the necessary ports. This is very cool.
So a razer core?
Razer core is too big, the idea is to use the mobile video chip.
