While there is something understandable about partially wishing for it, I don’t think anyone is going to lead a genocidal strategic bombing campaign against the United States to level every manmade structure taller than knee height before promptly having 95% of the planet embargo them for 75 years, so I doubt the US can emulate the DPRK’s economic situation too well.
What’s left to even sanction Russia with at this point? You can’t threaten someone with something you already did 4 years ago.
For what you’re spending on this, I would highly recommend throwing in a 1440p monitor. The difference from 1080p is night and day. The 7900XT will have zero issues with it, and you can find a solid 27" one for cheap nowadays so long as you’re not trying to find an OLED or something with a stupid high refresh rate.
That’s about the only feedback I have here though, the rest of this build looks good!
I think the general consensus among anthropologists is that the workers building the great pyramids weren’t slaves, just day laborers working for rations of ale and food.
