I know that the PC 71 (Black server case) mounts the PSU upside down on a ledge, so any dual fan PSU's have there intake fan pointing upwards, drawing the warm air from the top void of the case, this in itself isn't a particular problem just differant from the norm (facing down drawing warm air from CPU area) As far as I am aware this case does accomodate normal ATX PSU's, so what is it that doesn't fit properly?
