    I will have to get back to you on that lol. Still trying to find a few. If you happen to stumble upon any DeskMini GTX's let me know lol Those seem like a good bet but are very rare.

    There is also this though, but its very expensive.

    @Khenglish I have seemed to find a good motherboard at a decent price.

    https://ebay.to/2Z0JF35

    This also seems to come with a few wires shown in photo 7 of 7. Can you make out what all is there? It looks like SATA cables and a ribbon cable for something.

    Also the motherboard claims Type A or Type B MXM compatibility, up to 150W. I am unaware of this format, just MXM3.1, etc.

    MXM power switch transistor is boxed in red. Solder a wire bridging all 4 pins in the green box for the power cable. I am assuming that since this is a desktop that MXM power is 12V, and not the normal 19V like on laptops.

    Also only 1 transistor is concerning. That thing may explode with cards over 100W.

    Perfect, and this would still require the earlier mod to the MXM connection as well to support 10 series and 20 series MXM?

    Also assuming that pin 4 is GND?

    Don't ground that...

    Yes you need the 3 3.3V wires and the 1.8V enable wire.

    I could probably find it when I get the board, but you have an idea of where to ground the MXM external connection.

    You can ground it to anything that's ground. You also don't need to connect it at all.

    The person selling me the MXM GPU said Clevo cards also have a software protection as well as the 2 physical protection (fixed by the 3.3V connection and the 1.8V Enable mod assumably). Do you know of such software protection? Sorry for asking so many questions.
