What could I buy? $17,000 to spend

Save it.
Live your life like you want to, you biggest worry (money) is gone.
A lot of people are just stressed and depressed, can't do what they actually want to and can't chill down for a second because they are worrying about the money.
You don't have that worry anymore. Do what you like to, without that big thing in your mind what every person is longing for. Money.
