Bought a PC Desktop

After basically nomading for the last couple of years and living in Thailand for the past four years, I now find myself living in Barcelona—at least for the n`ext two years—and, for some reason, I wanted to have a desktop computer.
No, I didn’t build it myself; I just asked one of the shops around here that a friend recommended.
What reasons can I think of?
- I can play games again—the last time I played seriously was in 2015, ten years ago!
- I miss running Linux. I’ve owned various MacBooks for the last decade and enjoyed them, but there’s something raw about using Linux directly.
- It weirdly resembles some kind of stability.
Though I did buy an Nvidia card, which is probably going to be tricky when running Linux, but I’m up for the challenge.
