Oof. From what I've glanced, a CPU there costs nearly $70 and less performant models are actually costlier. Not sure what to do about that, so here's some general advice:
An AMD APU paired with a microATX motherboard is the cheapest way to get reasonable computing performance. The best thing I ever did was to buy only a motherboard, CPU, and RAM. For €90, I was blown away.
See if you can salvage any parts, there's no need for a case, SSD, and PSU every time. AMD has a nice upgrade path for this. A motherboard with AM2+ socket will fit an AM3 CPU. You can then later upgrade to an AM3+ motherboard and wait for a reasonably priced AM4 CPU, and so on. My gripe with this, however, is that it used to be possible to have different (scavenged) DDR RAM parts as long as it was the same number of pins. A quick glance at the notches would tell you if it fits and that was that. Nowadays you often have to have either just one bank or a few of exactly the same part.
Sometimes it's possible to get lucky, like buying a cheaper model CPU and succesfully unlocking an extra core. And a boxed CPU may be more expensive than a loose tray, but comes with an adequate cooler that'll fit just fine.
Neither of us have any contact details in the profile, although I'm not sure if I can be of much help to you anyway.
One more tip. If you see your box increasingly use swap during normal workload, adding RAM can significantly improve performance. Even if it's lower spec RAM.
