So I was digging around, and found a nifty looking cable.
https://cs-electronics.com/product/pcie-x16-cable-fully-shielded/
It is a cable with a seemingly small connector that allows the bridging of PCI-E x 16 signals. Could it be possible to say, transfer a standard PCI-E connector on an ITX motherboard, into a port on the back of the IO shield using a similar female port? The ability to hook up a true EGPU externally from the computer is very interesting to me, bypassing any throttling that may occur using a x4 connection, or even thunderbolt.
