I was reading in one of the computer magazines that they are altering the form of the motherboard which was ATX to BTX. This MB is smaller but will provide for better cooling with the cases designed for it which will have one big intake fan which will blow across the hot processor(some in test just used heat sinks) and main chips. The case and MB are suppose to be desined so the air flow is mor efficient and reduce the computer noise. Also smaller cases may become available. I just did a quick search on the net and found this here.
