I'm contemplating the purchase of a fairly large local storage enclosure using eSATA/Port Multiplier technologies. I will connect to the enclosure using one or two eSATA ports. First of all, is there such a board which will mount inside a standard ATX-type case and connect several (8+) SATA drives to complementary Port Multiplier enabled ports (2 ports)? Otherwise, I take it I'm stuck with a pre-built drive enclosure, then? I'm looking to store ~5 TB ideally.
