The best/safest way to do so is to found a company/club/... that operates the node. The goal here isn't to hide who runs it, it's to make sure that the police find someone who understands what Tor is before they find whose _home_ to raid. When there's bomb threats, child porn, or other illegal activity coming from your home IP, you're going to get raided before you get to explain what a Tor node is. When that stuff is coming from a server that you personally have rented, you're probably going to get raided before you get to explain what a Tor node is. When that stuff is coming from a server that a company, student club, or similar has rented, suddenly brains are required to be switched on since there isn't an "obvious culprit", and it's unlikely that they'll start raiding the private homes of random members or organizers. Not impossible, but significantly less likely. The office address of the company/club is at the highest risk, but if that's "digital freedom club, computer science department building, university road 17, biguniversity" that's not necessarily a big problem. A raid at the office address would already be the exception, not the rule, but if you can make sure that a raid happening wouldn't be more than a minor annoyance, do it. For non-exit nodes, just run them wherever you feel like, as long as you're OK with the traffic and the risk that some people will treat the IP as "not reputable". Anyone who finds the IP of the node will by necessity have an idea how Tor works and understand that the node is not the origin of the traffic.
