I always told myself if I ever became a "tech billionaire" I'd buy out a random abandoned town somewhere, setup high speed internet, and turn a ghost town into a high tech town, cause why not? You could easily become mayor and approve some reasonable projects. Sell extremely affordable housing for the buck (close to actual cost).

I do often wonder if it might be worthwhile to shove a bunch of server farms into a few abandoned mines, if you setup the appropriate infrastructure in said mines to protect your data centers.
