I'm just talking out of experience. The PSU is usually the noisiest part
in a computer if its heated, and if you put it at the top, especially
right above the CPU, it becomes too warm. I avoided this problem in one 
computer I build (an antec SOLO case BTW) by replacing the fan in
the PSU so that it pused air towards the CPU instead of the other way,
but the easiest way to avoid PSU noise is just to put the PSU
at the bottom.
