This desk has a great setup with the bookshelf on one end and the storage drawers below. Our space wouldn't allow for it to be lined up perpendicular to the wall like this, but it would still work (mirror image of this one, with the bookshelf on the left) lined up against the wall, with the upper free-standing shelves off center to the right, in front of the desk instead of to the side like in the picture.
This is a good, simple option with shelves above.
