Need rails for HD plus I cannot access the HDD slots. Also need power supply cables and directions on where to connect on motherboard. Appears that I need to remove entire front panel to access storage slots.

Your unit has a DVD and 1 TB hard drive. In order to add a second or 3rd hard drive you need the following:
1) HP Blue Isolation screws. These mount to 3.5" hard drive, and let the drive "slide" into the bay. You should have noticed them on the existing hard drive.
2) Special 2x3 (6 pin) SATA power cable, as explained in this discussion.

The EOL on the HP 795 will explain your motherboard. Nice pictures.
