I agree the weight would be too much if you used 2x6's or similar, but I was thinking using some 1 inch insulation and some masonite to lighten the load would work. I'm not worried about lifting the kegs in and out, but it is big enough where I use it as my primary lagering fridge as well, and the thought of dropping the 6.5 gallon carboy full of goodness is what I don't like.
Chances are I'll go with the lower mounted one though, just on the laziness factor and it seems a lot easier, with less chance of fucking it up.
