And furthermore, you can share your internet from your computer, if running Linux, to other devices via Ethernet or WiFi! There may even be a super hacky way to do it through Bluetooth as well, but I’m gonna assume that wouldn’t be worthwhile to pursue…

The bazzite project website has an explicit “how-to” for extra drives. Worked for me with no issues, though I am definitely more experienced with tinkering with that kind of thing.

Bazzite would be my suggestion. Throw the full install on the ssd then format the HDD for general storage. I’d be a little concerned about the 1060 3GB GPU though. Drivers will likely be fine, but the “10 series” have notoriously awful async compute and take a much larger penalty when running games/apps under proton/vulkan if I recall correctly.

Mine “hangs” for a while but does EVENTUALLY boot. It takes like 3-5 minutes though which is very unusual. It used to boot in a few seconds (nvme ssd boot drive), so at first I was worried maybe the drive was going bad.
