I have to agree with this post. as far as DIY projects go this will be very easy indeed. All you need is some wood, a saw, some sandpaper, glue and screws. I would also be tempted to add rubberized feet and some kind of felt topping as well. May as well varnish it to give it a good finish while you are at it. The bonus is that you will be able to make it in a way that is ideal for comfort, ideal for the desk it is being used on. Have you considerd getting a full sized USB keyboard for it? In my experience laptop keyboards are very uncomfortable for long-term use.
