Personally, unless you come across an incredible deal, the wine cellars are not worth it for beer, IMO. I currently have four beer and wine storage appliances:
Eurocave Confort Vieillitheque (large mohogany finished wine cellar)
Viking Wine Refrigerator
Vintage Keeper wine cellar
Upright keezer
The eurocave stores red wine, the viking white wine, the vintage keeper and keezer store beer. The eurocave and viking are great for how i use them (wine storage). The Vintage Keeper is a cheap POS that I'm ready to replace with regular refrigerator or an upright freezer to keep at fridge temps.
The big reasons are shelving and cost. As blizzard shows above, wine cellars are intended to store bottles on their sides. The eurocave is more flexible than what blizzard's is, but would still need some modification to the shelves to efficiently store upright bottles. I store bottles upright on the vintage keeper shelves, but i have to be very careful to place things in such a way that they do not fall over.
I nearly bought another eurocave this weekend off of craigslist, but decided better of it. The cheapest ones cost $1700 new, the one i have originally cost something close to $5,000. Even at CraigsList prices ($700) I could still buy a new upright freezer or refrigerator for the money and have workable shelving. Of course, the eurocave does better to keep humidity up so that corks don't dry out, but that's not much of a concern on the timelines that most people cellar beer or even wine, it's more of a concern with wine that's kept for decades.
