If the floor is carpeted, then that's a good dust prevention measure too. The air intakes are usually at the bottom of the PC, the rubber feet designed to lift the case above the surface tend to sink into carpet and every time someone walks by or the user shuffles their feet, dust is raised from the carpet and sucked into the PC. 6" seems to be the magic number for a quite dramatic reduction in the amount of dust sucked into a PC.
