Yep.  That's what makes it fun.

Yeah.  I was looking at the website for a company that sells obsolete
and surplus parts, along with new stuff.  Pretty interesting stuff.  A
lot of military, NASA and telecom surplus (www.surplussales.com).  Since
they are located only a couple of miles from me, I might have to go down
just to browse.

I didn't need to test them.  With the ones on the GigaByte board, they
were hot to the touch and the tops were bulging.  The ones on the Soyo
have bulging tops, and the electrolyte has been leaking onto the board.
