  How is a bottom mounted PSU advantageous?a) it sucks in dust, so you need to have a filter. If you mount a filter, the obstruction will force the fan to ramp up. Also, the filter's close proximity creates turbulence noise. If you keep some distance between the filter and the PSU -you will need to make the case bigger. In every way - this is inferior to the current design.b) in a Solo, a bottom mounted PSU will disrupt the otherwise perfect flow pathc) please don't mention the convection. If there's but one exhaust fan in a case - convection doesn't work!d) removing the PSU from the top will rise the CPU temps - as evidenced by the users who built ducts to the front of the case.
