I love this. But this is where we guys are short sighted. We only see a walk in beer cooler. If you really want this (and due to the price only the wealthy really have a shot at it i believe...) you need to think outside the beer cave title and present this to the spouse as a walk in refrigerated pantry.
I'll admit that you will lose 2/3 or maybe even up to 3/4 of the storage space to such other crazy items like (gasp) vegetables and (pitter patter) meat and cheese, but you'll still have PLENTY of space for bottles or cans of beer AND you get to have a keg on tap and cold all the time.
It's all in the way you present the product, i'm telling you!
