45 minutes later I had my old lid and screen removed and my new one installed with no tools beyond their provided torx screwdriver. It was amazing to be able to do that and not need to replace the entire laptop or mail it in for service! While I had it open I installed another 16gb stick of RAM to bump up to 32gb total.
I'm debating getting the upgraded motherboard... I may wait another year or two when the performance gap is larger and I find another purpose for the old motherboard. I could 3d print a case for it and use it as a home server, gitlab build runner or bench PC. It's really cool how flexible it is!
The raw specs are not the best, the battery life could be better, but I appreciate the mod ability.
