Here's an interesting problem. I have the Gigabyte K8N-sli pro motherboard which has 1394b firewire connectors. One of those connectors is being used for the included riser that came with the board. The other connector I want to use with the firewire port on the front of my case. The case is 1394a which doesn't seem to fit on the other motherboard connector. Is there an adapter or something so I can use the front firewire port?
