So as I'm working here I thought to ask if orientation matters or not. Currently my AX1200 is upside down, drawing air from underneath. In the next case I'm planning however, the PSU will stand on-end, drawing air through the front of the case and then exhausting straight up. If I recall, it's a ball-bearing fan so vertical mount shouldn't matter. But.. I dunno. Any more-experienced opinions about the affects of orientation on the PSU?
TIA
