So, it's a PC, right ?
It's a tower, and if you open it up I'd wager you'll find a microATX motherboard, a regular AMD video card and the usual components connected to said motherboard.
The one thing that may change is the way the OS is configured, locking you down to the Microsoft Store and only giving you the gaming options.
I wonder if you could install Linux on it. I also wonder why you would want to.
