    • Power down your Mac mini, disconnect all of the cables, and flip it over.

    • Insert the Jimmy into the crack between the aluminum top housing and the plastic lower housing.

    • The Jimmy should reach a stop about 3/8" down.

    • Gently bend the Jimmy outwards to pry the crack open a little larger and lift the lower housing up a small amount.

    • There are several plastic clips on the lower housing that fit into a channel in the aluminum top housing. Your goal is to use the Jimmy to push these clips inward enough to free them from the channel, while gently pulling up on the lower housing.

    • Once you have the first side free, rotate the Mac mini and start prying up on the front edge.

    • Use the same prying motion to both bend the clips inward and lift the lower housing up out of the top housing.

    • Later in this guide you will remove several recessed Phillips screws. Bit drivers are generally too large to fit in the recesses, so be sure to have a thin shafted Phillips screwdriver on hand.

    • First remove the AirPort antenna (the larger of the two), located near the power button.

    • Slightly squeeze the two retaining arms toward each other and lift the AirPort antenna off its post.

    • Squeezing the two posts excessively will surely break them off the internal frame. Work delicately.

    • During reinstallation, you will have to slightly squeeze the two posts together so they fit into the openings on the AirPort antenna board.

    • Use the tip of a spudger to slightly lift the left side of the ZIF cable lock up from its socket.

    • The ZIF cable lock will lift about 1 mm and stop. Do not try to completely remove the ZIF cable lock.

    • Lift the audio board ribbon cable up out of its socket.

    • If it refuses to lift from its socket, the ZIF cable lock is not fully released. Make sure it is evenly lifted about 1 mm from the socket on the interconnect board.

    • Use a pair of tweezers to lift the hard drive thermal sensor cable connector up off its socket on the logic board.

    • Use tweezers to grab the connector (as seen in the picture), not the wires.

    • The connector is located under the optical drive opening, next to the PRAM battery.

    • Push the PRAM battery toward the center of the logic board and pull it up out of its holder. You'll have to push the battery in further than you'd expect in order to get it to pop free.

    • Don't bend the metal finger too much or it will break off, requiring a new logic board.

    • When inserting the new battery, make sure the side with writing along the edges faces the black plastic holder. You should also ensure that the metal connectors make contact with the battery (you can bend them forward if they do not).

In step 18:

“Remove the single T10 torx lug securing the logic board to the bottom housing. “

This is not a T10 but a T15 torx.
