I did not know that - my point is that system76 is not at all sketchy about it. They actively encourage tinkering, make it clear that you won’t void your warranty, and have extensive technical documentation to explain how to do upgrades etc
Upgrading/tinkering doesn’t void your warranty. Explicitly.
And their customer service is top notch. I thought I bricked my gazelle when I upgraded the memory, but their customer service walked me through how to fix it - didn’t even bat an eye.
