Continuity mistake: When Gibbs visits Abbie's lab to ask about the smoke detector and computer, he finds the CPU disassembled on her table. The "hard drive" is placed on a white tray in front of the cover, which has been removed from the CPU. Initially, the hard drive is white in color. However, in the close-up shot, it turns black and looks like a different piece altogether. Furthermore, the white tray disappears, and the hard drive sits on the CPU cover. In the wide-shot, the white tray reappears, and the hard drive is again white as it was originally. (00:24:50)
