Just got my hard drive yesterday. I'll take pictures when I get home this afternoon or tomorrow. I decided to go with a 2.5", 320GB, 7200RPM, 16MB cache WD Black Caviar drive with the mesh enclosure I linked to. It is so compact and perfect for my needs. The mesh seems to be keeping the drive very cool. The enclosure has a blue LED when it receives power and a red LED when it has activity.
