I have heard that the Thinkpad X200 is a good laptop for people who want to install libreboot and disable the Intel Management Engine.

This is another article about the IME. It lists libreboot compatible computers

Despite all Intel's efforts to make the Management Engine inescapable, software developers have had some success with preventing it from loading code. For instance, the Libreboot project disables the Management Engine by removing all the code that the Management Engine is supposed to load on some Thinkpad computers manufactured in 2008, including the R400, T400, T400s, T500, W500, X200, X200s, and X200T.

Also, many Intel computers manufactured in 2006 have the ancestor of the Management Engine which is disabled from the start, such as the Lenovo Thinkpads X60, X60s, X60 Tablet and T60, and many more.
