After that fiasco and expense we decided to just move those systems to less critical jobs since just remoting into one of these Mac Pros would cause a GPU panic. Since the failures were intermittent Apple could never be sure the correct part was replaced (of course it wasn't the correct part). The free repair program replaced both GPU cards, but if a system did not qualify for the program Apple would only replace one card at a time. Our organization has a number of these systems and almost all of them ended up having Kernel Panics from time to time related to GPU issues with some systems having quite frequent panics. Third, as far as I can tell all of the different model GPUs for this Mac have issues and not just a small number of certain ones as was covered by the free Apple GPU repair program for the Mac Pro 2013. Also many of the places you tight screws is extremely soft metal so it is very easy to strip the threads. One thing is the top & base are round with the middle being somewhat prism like in form. It is a very tricky thing to do for a multiple of reasons. Second, the whole computer will need to be disassembled. First of all there are two "GPUs" in this Mac Pro.
