reccomendation for firewire connection

You linked to a list of products, but assuming you pick up a PCI card yes you can do it.

Pop the side of your case off, find an empty PCI slot (white), unscrew the rear panel cover for that slot (you won’t be re-using it), plug card in, put screw from rear panel back in, put the case panel back on, open beer :jam:.

Edit: Turn the computer off first :smiley:
