Interesting idea. But really only works for a specific type of PC build where the motherboard and GPU are back to back. I feel it would work better as a bottom edge connector where you could then also use a 180 degree adapter to get the same results as this. But then would also allow for some other configurations. Such as a 90 degree adapter that would put it back into more of a mATX standard mounting or -180 degree and vertical mount in front of the motherboard as is more common. With the connector on the bottom, the riser adapter/cable wouldn't then be covering up any connectors or M.2 below the PCIe slot which is common with existing motherboard layouts.
