@zoiee2020 and @alexjaynem Looking at the prices, I noticed that certain CPUs were actually much cheaper than I'd expect, for example the Ryzen 5 3600. I think that's because it can't keep up with the newest-generation graphics cards, but it's certainly more than capable of driving a 1660 Super or 2060. As a bonus, the socket it uses, and therefore the motherboard, is compatible with the current Ryzen 5000 series CPUs, meaning the build would support an upgrade to a much stronger processor in the future. So it's an excellent choice for someone on a budget now but who'd like to have options in a few years that don't include building from scratch.
RAM is also still quite cheap, as are solid state drives. Graphics cards, not so much. That's where it might be easier to buy secondhand from someone you trust; if you're willing to wait, that's fine too, but it might take a while for the market to sort itself out. The motherboard prices seem like kind of a mess, but I didn't look too closely, I just picked a decent board with enough slots and that supports fast RAM.
Anyway, @alexjaynem any time you have questions about a specific component, please feel free to ask.
