And here I am thinking I had a moment of inspiration..
So this means it's definitely possible and not just for a nanobrew setup. I just wish I could see the pictures of that.
Just had this crazy idea while reading the thread on hbhoss' project. Ive seen websites about storage containers which have been converted into homes. I don't see why this wouldn't be possible. I've seen them as low as about $1500, and "insulated" models are also available. Any thoughts?
