Home link on Nav Menu

When I change the case from lower to all upper on the Home link, the menu bar does not reflect the case change. Is there somewhere in one of the template files that it is hard coded or somewhere in the CSS? I would like all of my menu links upper case and the home link is the only one that is left in lower case even though it is upper case in the Wordpress page title. http://mobilemakerspace.com/ Thanks!
