OK, I just got my PCI sound card today, and it doesn't fit in my Power Mac! It's a June 2004 Power Mac with PCI slots, and the card was advertised as a PCI sound card. It was cheap, and I bought it mainly for fun, but it doesn't doesn't fit. The pins don't line up, the little black plastic divider is in the way. Any ideas what's going on here? What kind of card have I got?
