I own this laptop, it’s awesome. The only complaint I have is that the battery really functions more as a UPS. The System76 support is really top notch too.
I will say I'm impressed that the fan can't be picked up by the mic, I wonder if System76 did any custom work there. I wear cupped headphones so I don't hear it much myself. Did you have the fan problem though, just curious? Maybe I can decrease the fan speed in the BIOS...
I use an external webcam with an external monitor most of the time.
