Wine Cellar and Wine Storage

We just bought a new home up in the mountains and we actually have some space (versus cramped apartment city living). There is a whole area downstairs that already looks like a wine cellar - it just needs some racks. The temperature stays pretty even all year long but the humidity probably changes too much for long term storage.

I was reading through this report about wine storage. Probably overkill to have serious software and a wine cellar unless your collection is worth something or if you are trying to age the wine properly.
