Can you advise whether you can build or buy yourself a good PC in the region of 20 thousand rubles?

Hello everyone, tell me is it really possible to buy yourself a good gaming computer in the region of 20 thousand rubles. For example, just recently I came across a site where you can buy good PCs in the region of 20 thousand, I also stumbled upon a site where you can actually buy a good assembly in the region of 40k rubles and more) Also, even if you look at Avito, then there are really top-end machines in around 20 rubles, on Avito these are publications of some companies that allegedly collect powerful hardware and sell for such a cheap amount as I understand it) So is it real? Maybe someone even bought the same assemblies on Avito?)
