Yes, I had a Clevo-produced System76 model and I've had multiple hardware issues with it -- for starters, it failed to POST just days after receiving it, and System76 support did repair it, but they were not very accommodating about it, saying there was no way for them to provide a shipping method faster than ground even if I paid for it, etc. I want to like System76, but the truth is that my experience with them was disappointing.
