This is Scott McNealy's house, the guy who founded Sun Microsystems and sold it to Oracle Corporation for $7.4 billion in 2010.
Although McNealy insists he's not a billionaire, he pretty much lives like one. McNealy built this home over a period of seven years. It's a combined 32,000-square-foot, four-level estate nestled in the hills of Palo Alto, California.
Set on 13 acres, the house and property are stuffed with all kinds of recreational activities, including a 7,300-square foot pavilion "that can host car collections, ice hockey, tennis, horses, gymnastics, art studios, you name it," according to the listing.
