air-wire it instead but it might look a bit messy).

Those do look convenient,

Not really, you need too many of them for a decent wattage.

You'd be a lot better off with resistance wire or bulbs.

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..

That wire is clearly in use from the power supply.

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 ?

Yep, thats why there is more than one say 12V wire.
