How is this for gaming?

NOT good. You wanna run older game on medium settings it will do fine. Anything new, no way.

Is the 8 gb DDR4 one piece, can you make it 16 gb DDR4 by adding just one piece of 8 gb DDR4?

Anyone have any experience running Linux on this PC? I think it should work like most PCs out there, just personally curious
