We're getting down to some serious deconstruction now. A few SATA connectors come out and the hard drive bracket is free.

These SATA cables connect the single or double hard drives to the motherboard.

Next up is the hard drive thermal sensor, which doesn't put up much of a fight.

Rather than taking Apple's approach, who changed their SATA connectors to a proprietary 7-pin design and embedded the thermal sensor inside the hard drive, HP is sticking with an upgrade-friendly design with standard SATA sockets and a thermal sensor that's mounted on the computer's internal frame.
