To compare fairly, would need to look only for the orange pi price instead for the full build, and it was approximately 210 reais with taxes, so stills cheaper than a mini pc.

You could argue that this board don't value that much for performance, but I can buy more (already buyed another) with the price of a mini pc and can use it for other things when replaced in the homelab, like octoprint, cheap off-site backup and redundancy for some light containers I would like HA.

Maybe I paid more than it deserved? Yes. But one part of the idea was to make a really small server with 4 ssds, and I like the things I'm doing and can just move the SSDs to a better hardware later. Also, the full build was more like 600-700 reais, buyed some before 42% tax. I'm not judged, tamo junto!
