I needed to take apart a my precious Thinkpad today. (The poor thing is getting on in years, and I needed to swap out its CPU fan.) It struck me as I was taking it apart. (something I've done many times) I don't know of any other puter manufacturer that makes it this easy on you. This is a primary reason I love the Thinkpad. It's like the Jeep of computers. Simple, easy to service, uses basic, standard parts and screws.
