Put it into a high yield interest account until June 8. Then give money and interest to me as a wedding gift

(It might be smart to take the money out a few days before

).
For real though, put it away. ING has a decent savings account, as do a couple others now (HSBC and Emigrant are the ones I know of). 5% interest could net you a decent amount by the end of the year to buy yourself a nice computer and still have money left over from the sale price to buy whatever else.
