4JNA, you've said you've done it successfully, so now I'm interested again!!!!

I'll look at your pin outs again and check. I am concerned about Firewire. We use external Firewire 400/800 drives (OWC Mercury Elite Pros) and rotate them every 2 weeks. I guess you meant bus powered FireWire? And as far as ADC, this unit will be headless, so I wont even need a display.

Also, any particular ATX PSU you selected? Recommend?

Please let me know, gears are a turnin i my mind!!!

Thanks

Rob
