Is it really simpler and more efficient to have 96 individual power bricks with custom mounting hardware rather than one (or a few) larger, high-efficiency AC to DC converters and just distributing DC within the rack?
You would have to terminate in magsafe connectors. You'd either have to butcher the wiring on all the power bricks or come up with some frankenstein thing with airline adapters, which I believe are now discontinued for some reason.
I'm guessing it's because airlines are moving toward just having standard power jacks. In fact, I can't remember the last plane I flew on that actually had the power jack the airline adapter needed.
