Hi folks. I am a new RFM owner. I have a bone stock RFM with firmware 1.2 on it. I've already ordered an update stick. What else should I do first? Any "must have" things I should be looking at? Can I put a new model power supply in it or does it need one of the old school AT style power supplies. There are dangerous noises coming from the old one so it is time to do something about it. Everything works on my pin right now but I'd like to make sure it continues to do that for the foreseeable future.
