What i'd really love is if there was a service where I could pay a technician to take previous generation Macbook Pro with it's excellent keyboard and no touchbar and transplant a new logic board with modern 8th generation intel processor, 16gb of ram and an nvidia max-q gtx 1070 (or AMD equivalent) into it, complete with working USB-A ports. I wonder if it could still fool MacOS into thinking it's a real mac without having to go the hackintosh route. That would be the perfect laptop. Does anyone know anyone who has done this? Could you get something like that done in China?
