Damn, looks like you got bit by the same bug as me. I did one batch of Mr Beer and started a project that has turned into a monster. I have to go slow because of my budget restraints, but I am having a blast getting it all together and planned out. I'm working on the controls and plumbing in my three tier tower right now. I think copper is my new best freind for all the plumbing, and conduit for wiring and sensors. Have fun along the way, I am havin a blast...
