Welcome to FreeNAS Forums. I can see that you have met a few of the mods/admins already.
I'd like to say a few things... Do a lot of reading before purchasing hardware for your system. If you are using old hardware then you need to be aware of the pitfalls by using that hardware. If you have a question, try a Google (or your favorite browser) and include "freenas" or "freebsd" depending on the question and you might be surprised on how much information there is online.
I hope you experience with both FreeNAS and the forums is a good one.
