My case from www.internetishop.com had a wiring harness which acomplished this essentially transfering the rear connectors to the front. Maybe they have something specific to your needs.
My new home built PC case (with a Shuttle main board and AMD 2400+ processor, 512 Meg RAM) has two Firewire knockouts on the front of the case next to two (of 6 total) USB 2.0 ports. I'm looking for a PCI Firewire card that will connect/attach/adapt to the knockouts on the front of the case. All Firewire PCI cards I can find on the net have the ports on the card, which will be behind the PC. Have I just not found the one with ports on cords that will attach to the knockouts?
