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

    • 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.

    • In the next few steps you will be removing the AirPort and Bluetooth antennas (shown in red) from the internal frame. Be very careful, as breaking the brackets will require replacing the internal frame.

    • 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.

    • Grab the Bluetooth antenna nearest the port side of the computer by the edges of the board and pull it straight up off the internal frame.

    • Pull carefully, as it may offer significant resistance and release suddenly.

Sure wish I hadn't seen the photo in step 14 of the appearance of prying off the fan connector as Ron states here in the *uckup section. I also appreciate ifixit for following Ron's suggestion......ha

I’ve just done the very same thing. But I’ve just ordered a new interconnect board and will follow this - Mac mini Model A1283 Interconnect Board Replacement very carefully. What I’ve just learned is to read the comments for each step individually before attempting it. And that my eyesight won’t let me do this kind of thing in a few years.
