I decided to come back and give Framework another shot, following my issues with Lenovo.
I ordered a new AMD 7840u mainboard, a set of 2nd generation hinges, and a Coolermaster case so I can continue to use my old mainboard as an appliance PC.
So far so good on the new mainboard and hinges. But the coolermaster case is defective, with what is seemingly a common problem with bad tolerances as seen here: Cooler Master case fit issue
It’s crazy to me that this keeps happening. This thread is marked [SOLVED] because I no longer have permission to edit the original title or post. But Framework’s quality control issues are far from solved
