yeah that 575 main board is worth it...
Question ... before you fired it up... did you take it to the garage fire up the air compressor and blast out the monitor and fan areas real good?
i can't tell you how many computers i "FIXED" just by blasting out the filth!
in your case it sound like a cap blew...
i had an apple IIe once, i had just gotten it in from ebay, fired it up, I'm using it, and smoke starts pouring out of it, tons of smoke!
it's still working buy the way haha, so i quickly unplug it, opened up the psu to find some large rectangular object split open spitting what looks like oil all over... not sure if it was a cap, or oil filled resister... but it was nasty!
