Open source, no. Free to use, yes. ISE Webpack supports S6 with hard PCIe blocks.

Unfortunately I've removed the webpack from this laptop as I wasn't using it much and it takes up hellalottaspace. Not to mention (yet I did) the 15G extra needed every time there's an update.

I thought there was SATA, PCIe and USB cores available in webpack, but maybe I'm wrong. An audio interface isn't much work, it could simply be a memory mapped buffer writing at 48/44.1kHz to S/PDIF and I2S.

Running SATA and PCIe at the same time is tricky as the clocks are different, but given a big enough FPGA it's at least possible. S6 doesn't do a whole lot of lanes anyway, afaik. And K7 is not exactly cheap. An S6 design should be possible in the ~5W range, same as FCH.
