Not sure wtf it is but video confirms it.

Damn fan isn't spinning for nothing.
Belt is burning on crankshaft.

I'm figuring it's the alternator but any other thoughts?

Sure seems to be the culprit. A loose fan belt would of course prevent the fan from turning as well, but that God-awful noise sure sounds like a fried alternator bearing.
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
