Thanks very much everyone for the input, though I have thought long and hard about this today and for the past week and have decided that the thru-the-collar way just doesnt do it for me, I need a big tower... but biermuncher,
I shouldnt be limited because I plan on making a pass - thru tower , which is basically a T style tower, but instead of one vertical post in the center of the Tap-bar, there is two vertical posts on the ends of the tap bar. Its more shaped like this: i=i with 5 taps going across the equal sign.
so anyway the left vertical post will have a fan built directly inside it , pulling the cold air in from the freezer then the right post will have the beer lines coming up. so the air will come up through the left post, across the tap-bar, and down the right post. nice cool beer lines is what I will have
Also , to fix the problem about not having acess to the taps when I have the lid open...
I think If I create a mechanism that will allow me to totally disconnect the hinge from the door I will be able to slide the door over or back so the taps are still accessable and I have access to the inside, of course I will only unhook the hinges when I am cleaning and need access to both the taps and kegs, otherwise, if I were only adding a keg or something, I would keep the access system in swing open mode.
this baby is going on casters so i have no worry about wall clearence either...
what do you all think?
