I'm don't think that the connectors are different enough to care about - I had (in a previous life/system) a PCI SATA interface card that had both internal SATA and an eSATA connector, and when I ran out of regular internal SATA connectors, I just used a regular SATA cable, plugged into the eSATA port, then ran the cable back in through an empty expansion slot in the case, and hooked it up to a regular internal SATA driver - worked like a champ... ;)
