Also, Raspberry Pi first got popular because of the size and cost. Now it's popular because it's popular. Not hating on them, I think they're cool, but they're not cheap any more. Especially with the scalping.
Getting x86_64 based systems is going to mean much less headache. Unless you truly truly need the size I wouldn't consider getting a Pi or other SBC. Just go to literally any used marketplace (Facebook, Craigslist, etc) and get anything.
