This only has a PCIe slot. If you need FireWire you will have to have a PCIe card type. PCI will not fit.
I have a PCIe FireWire card installed in my desktop as I use it in my recording studio.
Although the documentation doesn't show it, this appears to be a slim case model and if that is true you will need a "low profile" PCIe FireWire card.
