I have been keeping glasses in freezer of upright kegerator(holds 5 kegs)mostly to keep clean glasses. In summertime I prefer a cooler glass, wintertime not so much. Maybe just a nice cabinet would be better for glasses rather than try to work around condensation problems. Have seen comments of problems with towers and warm lines also, fans installed etc. Can always put a couple of glasses in lager frig in storeroom. Maybe a collar with taps, build it under a counter/bar and roller frame under keezer for access.
