Free PCI firewire card. Just take it!
I have a PCI firewire card. It's PCI. It's firewire. Maybe you have a Pentium III machine that you want to edit video from your standard definition MiniDV camera (that amazingly still works) on or something. I don't know. I sure don't want it... but I feel bad throwing a poor defenseless expansion card away. He didn't hurt nobody.
