Check out the grow box in my signature, it may give you an idea or two on how to set yours up. Not a coke machine, but a BIG box.. One thing, you may want to consider using your fans to exhaust and let them pull fresh air in. In otherwords ditch the input fan.. Also exhaust at the top and pull your cool air in on the bottom.
