The Brutus 10 is expensive, even to build it yourself.
I'm just throwing my .02 cents out here.....but I would say to use the Brutus 10 design to help guide you. There are a lot of different ways you could build your stand (sculpture). You don't necessarily have to have the integrated gas lines and the plumbing right away. In fact, I would reccomend that you don't plumb it at first. Just use it solely as a stand for now and brew a few batches on it. Once you do a few brews on it, you'll start to figure out just how and where you want to mount all the extras i.e pumps, clean out valves, chiller, any electronics, etc.
And if you want some mmore inspiration for your stand, go here:
