Good points on making up the PCB with ENIG, it will definitely last longer.
That said i went with the cheaper option while prototyping and see how long it lasts but ill add that note to the github notes.
They are pretty quick to make as a cheap diy, so easily replaced worst case.
The other discovery for version 2 is that using 0.8mm pcb thickness is much better.
The card was able to push deeperinto the socket. Where as using a 1.0mm thickness worked, but poked out a little (it was still nice and firm tho)
It was only an extra few dollars to get 1 x set of 0.8mm and 1x set of 1.0mm. The only disadvantage is that the 0.8mm is
bendable/flexible which is ok but might be less ideal for the vga, ps/2 sockets.
There could be merit mixing it up and using 0.8mm for the laptop socket side and then using 1.0mm for the vga ps/2 daughter pcb - but for simple build 0.8mm is the way to go.
I made a simple case cutting up perspex, drilling holes and using plastic pcb stand-off.

While i still to run through a few more tests, im more than happy if you want to design a 3d printable case for others.
Let me know if it would help for me to make a larger pin 'sandwhich' footprint pcb to support other later models (using the same principles as this) with a idc connector footprint before i move onto my next projects.
