I am guessing here but I have been looking and the 7.2 looks like it will fit 4 soda kegs. The ones I looked at had a large shelf not good for much more then keeping some bottles or supplies. You may be able to find one with a smaller shelf.
One thing to consider is how are you going to lager? If you are planning on carboys you may be limited with the smaller freezer. Seems like I read something on using a big freezer and splitting it to serve on one side and age on the other. Some kind of duel controller with a heat source or something. Way too many things read sense then. You may be able to search it up on the net if luck is with you.
And remember when you drag that new freezer home and she complains about the size tell her it is only 14 feet and not the 25 foot one you decided to get at the store.
