I'm considering experimenting with making replacement cables from standard insulated ribbon cable, same as the 80-conductor IDE cables of yesteryear. The drive connector is low profile SATA power and data, the connector on the Logic Board is a Molex connector, possibly a SlimStack fine-pitch 22-circuit board-to-board connector. The hardest part is building the solid platform to solder the connector and wires to, although I don't see why a business specialising in printed circuits wouldn't be able to make something suitable.
IDE or SCSI cables of yesteryear will probably last forever.
