I would build the best possible gaming PC ever, and then spend a week rummaging steam for everything I like. Then I would make our house better, keeping it the same size. I would then buy a helicopter and a golf cart, which are street legal without a license in my town. Then tons of legos. and then I would use the rest to make my life exactly how I want it to be, college I want, Job I want, house I want, car I want, all the rest. Charity too.
