I wanted a sleeve for my Dell Inspiron E1705 (which is basically the same machine as the Inspiron 9300/9400) but couldn't find many good reviews online. Some said it would fit in XYZ sleeve and others would say it wouldn't fit in the same sleeve. So, I traveled to a few local computer supply shops and found several things. First, OfficeMax/OfficeDepot suck for laptop sleeves. They have lots of briefcases.
