@johnnyboy2098 The first laptop's hardware is even slower than most of the ones you linked in your first post: it's more or less the 2019 version of the first and fourth laptops' processors, AMD edition. You could do a lot better even for the same price.
The third computer has a processor that's essentially the same, just a year older and slightly less powerful, than the CPU in the first and fourth options you linked. It's more expensive because it's an all-in-one, complete with a decent screen. But it's not a proper desktop: it has laptop hardware and is similarly not very upgradable.
The second option doesn't list its exact model of processor (a red flag all by itself), but given the other details, I would guess the processor, and therefore the computer overall is about ten years old. Someone stuck a six-year-old graphics card in it, one that could probably handle Sims 4 on ultra graphics settings, although it would be a close call even if the GPU is in perfect condition. It also has a slow mechanical drive rather than an SSD.
There's nothing wrong in theory with keeping products like this out of landfills for a little while longer, but don't be fooled into thinking this is a proper gaming computer or even a reasonably fast everyday machine. It's not, and it's also old enough that it might not last very long either.
I still think the Victus you found or the two laptops Iinkd are clearly the best options of this group. If you'd like me to look for good desktops, I can, but I'm not likely to find anything that's enough under $600 to also allow for a decent monitor. Still, let me know if you'd like suggestions.
