New Computer Desk for my Dad

Got my dad a computer desk, need to get it put together later for him. It's a nice one, a Sauder desk with a hutch over it. There are recessed ends on it, and my mom and I were talking about how good they would be for putting in small shelves added onto the desk so that we could put small knick knack type things on display on the end of the desk. Should look really sharp when we finish it.
