Mostly it boils down to three categories:

• Case build quality. This seems a be a frequent issue among System76 laptops; in my case (no pun intended), the laptop case was very badly made and easily broke. I carry my device around very much, always in my backpack, which has a padded laptop section, and in a fancy padded laptop case (or bag or whatever the word is—arg). I essentially have double padding, and I have had a good experience with this padding and previous laptops. This time, however, even simply putting the backpack down, was enough force to dent and eventually completely crush the empty corners next to the hinges. I had to manually repair the corners very often, but wasn’t able to prevent damage to the hinges and stripping the threads holding the hinges in place. No other laptop, even ones much cheaper, has ever presented me with this problem, and it is extremely frustrating that the laptop isn’t designed to be even mildly rugged.
• Faulty motherboard and bad quality-control. The laptop I bought had two M.2 NVMe slots, with only one occupied. I was planning to add one of my existing SSDs into the second slot. The second slot, however, did not work. This is such an easy thing to test before shipping it, that it really left a bad taste in my mouth.
• Faulty part and known issue. After about two weeks of using my laptop, the touchpad started malfunctioning. I looked the issue up, and, well and behold, this was a well known issue with this specific laptop. I contacted support and the problem remained unsolved. System76 released and continued selling a laptop with a known, unsolvable issue. This was the final blow, and I totally lost trust in the company after experiencing this.

Forgive the shitty writing, I’m doing this in my phone.

Hope I was able to help, kind regards.

Do elaborate

I’ve got a galago pro that’s a little over five years old now, and I’m still pretty happy with it.
