Unfortunately then you have to spend $30'ish for a serial-to-parallel adapter for each of the drives that you use there. Probably better off getting a good PCI RAID card if you really want to go that route, but it depends on each person's situation. That's one of the good things about the NF2 - you likely don't have too many PCI slots filled anyway because of all the on-board goodies, so, getting a PCI card for something you really need shouldn't be a problem.
