The Taobao seller has started to develop a solution for, small cables that bring the Oculink connector off and away from the device's m.2 riser (often located in an inaccessible place) and able to be placed into an accessible place with some modding.
So far, the following customized cables are being made: Thinkpad series 14 and 16, Acer Shadow knight, Asrock DB9 port, GPD WINMAX 2, and a few others which don't have specific hardware associated with them.
With all of these though, the host device still has to be modified to place the Oculink connector in an open position.
I believe they are open to engineering new versions for basically any device. It's possible one of the existing versions might work for Steam Deck if someone wants to try (the riser could be cut down to 2230 length).
Is this M.2 with oculink extension sold anywhere?
