Personally, I would skip the "factory" and get the 003 and put the money towards a faster iMac and go with 4 gig or RAM. Then get a simple FW800-FW400 cable to attach the drive and daisy-chain with FW400 to the 003. Assuming these guys ship overseas:

look down the right side column for drives with 2 FW400 ports to make daisy-chaining easy.
