Just make sure that after he builds the platform for the keg to stand on that he has enough depth for the keg to sit in there as well as enough height for the keg plus atleast 6" of clearance for the tap and to allow for the beer line to gradually bend instead of kink
Oh, and make sure that if he wants to put a nice big tap handle on there that he make it low enough to accomodate the opening and closing of the freezer door but not too low. I had that problem with mine because I bought my convereted fridge minus tank and regulator for $25 but did some little upgrades to it so it wasnt so bubbafied
Oh, and freezer storage is good for this too
