The motherboards with onboard raid are even better. You can have 4 HDs on individual controllers. All of my systems have /, /usr/src, and /usr/obj on different HDs for performance. The new round ATA-133 cables even get rid of the air flow problem. They are typically 24 inches long instead of the 18 inches max on the ribbon cable.
