More assembley done, and some wiring. Customizing the power feed with solidered connections and marine grade shrink wrap. Ran into a slight problem. I don't think the power supply has a 5v+ rail, which means the 2.5 drive is not going to work, or a work around is done.
That motherboard has an onboard SATA Power Connector, right next to the black SATA Port 0 connector, providing both the 12V and 5V needed for 2 hard drives. I don't know the current limits, but I would suspect at least enough for 2 notebook sized drives, as the included cable has 2 plugs on it.
