I live in Brazil too and bought a R$120 old HP computer running Windows XP on MercadoLivre. Works decently enough for a Minecraft server after an upgrade (4 to 8GB of RAM). Old computers are great for price and they’re good if you can upgrade them.
For general purposes, get something better than what I bought since it is not the fastest (even though it runs the Minecraft server software alright, it still lags). Maybe upgrading with an SSD would help performance.
Minecraft: Java Edition
Universe Sandbox²
Subnautica (never played it, but heard it’s fun so I might like playing it in a desert island surrounded by ocean)
Deltarune (I’d have all the time in the world to wait for the next chapters)
ENA: Dream BBQ (same as above)
