Sorry for the originally poorly-worded question. I tried to improve it.
I asked my first question the other day on Gaming.SE regarding system requirements for a Minecraft Server. I conveniently found two tags: system-requirements and minecraft-server. This, I thought, gave me strong assurance that my question was appropriate for the forum.
And lo' and behold 2 days later, it's been deemed off topic.
So my question: Is it possible for a question to perfectly fit established tags and still be off topic?
And my second question: since this could apply to ANY SE site, is my meta question also off-topic? :)
