I have a 7700S dGPU (1st Gen) for the Framework 16 I no longer use and would like to sell. Works flawlessly and no physical damage, I just switched to an expansion bay instead. $300 (plus shipping) via PayPal. Selling in US.
Disclaimer: You WILL need to either already have in your possession a graphics module interposer (here) or purchase one from FW for this to work ($29 as of writing this post). An expansion bay shell interposer will NOT work.
