Something like the following might be
convenient, especially if you have some large heatsinks
lying around (or reasonably thick aluminum sheeting, say
0.1" or thicker) and can put it all onto your own PCB
(though if screwed or bolted down I suppose you could
air-wire it instead but it might look a bit messy).

Those do look convenient, but as I will be air-wiring everything, I don't
think it would be possible. I mean there's no way that wire small enough to
attach to the terminals of that package, would handle 1amp, letalone 24A.

That may be my problem in general.. finding and working with wire that will
handle such a high current.. I would assume the 24A from the PSU would be
combined from all the molex connectors and I couldn't draw that from a
single connector ?
