Some addition to my post:
The computer I found is a Fujitsu Esprimo Q957. I’ve read online that they are very power efficient and don’t draw as much. I will probably run some lightweight task almost 24/7 and sometimes heavier tasks for short periods of time. A raspberry pi is for me too expensive for the average specs, even if it is very efficient. I think a upgradable pc or mini pc is best, because they are cheap, but can be easily upgraded without buying a whole new computer.
I am thinking about buying a home server for a wide range of things. I found some cheap old computers on amazon for around 80-90€. Is it worth it to upgrade them with another stick of ram or a larger SSD? 2 8gb RAM sticks are only around 15€, so that would be 100 in total. But my question is, is it worth it, or is the CPU the limiting factor. Some of them have one from the pentium series.
Also, is 15€ for 2x8gb DDR4 RAM normal (not too cheap)?
Maybe you have other ideas for a cheap home server. In my case I don't think a 90€ raspberry pi is worth it
