Anyone know of a (cheap) blow-through ATX power supply that would fit into a 2HE case?
This case expects you to put one in that is "blow through front-to-back" style. I've not seen one of these power supplies for probably ever.
The rackmount case I've here is basically similar to this one here (but without the cutout holes on the top, but even if it had them they'd get covered by the case ontop of it anyway).
