Don't let these RIMS and HERMS components scare you. They are all pretty easy to get a grasp on and really only take a little bit of time to really understand.
I built the Backwoods Brewery, which was one of the Pimp My System rigs a few months back, after about 2 months of research. If you have any questions regarding setup or anything like that, send me a message and I would be glad to give you a 'checklist' of things.
