A used ASRock 6600 XT Phantom Gaming.  I used this GPU for a few months in an eGPU for my Macbook.  It did and still does work great and has never been used for crypto mining.  I didn't put the GPU under too much stress playing games so it functions as close to new as you could get.

Has a very minor dent in the heatsink.  A single layer is slightly bent and the tip.  It's virtually impossible to see and doesn't affect preformance

Comes with the original box and packaging.  If you'd like any more information or would like more pictures, just let me know
