UPDATE WITH PICS:
I used an old PCI bracket case cover for the mount plus the sata to esata adapter pictured earlier in the thread and a power connector off of a damaged ms28 drive for the power connector soldered to an old drive power cable. I shaped the PCI bracket and mounted the connectors on it then bolted it to the 360 chassis infront of the HDD area.
Internal to External sata and power connector completed.
Shots with case on.
The blue jumper on the power connector is to stop the power led from blinking when the Drive is not installed since this is a jtag 360 the drive will rarely be required.
Next step is to clean up the enclosure and repaint it.
