    • 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.

    • The two Bluetooth antenna boards simply lift off the internal frame.

    • 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.

This card is unsupported in macOS Sierra, so this device is outdated by Apple, however folks have been able to replace the card by a "compatible card" and patch the macOS Sierra install app, to actually install sierra on this version of the Mac.

I would appreciate if iFixit could provide a guide as to which cards could work, especially in terms of the size/dimensions, in this unit.

I just successfully upgraded my Mac Mini 3,1 (Early 2009) to the BCM943224PCIEBT from a Unibody MacBook A1278 and everything works swimmingly on macOS Sierra 10.12.

As an Apple Certified Mac Technician, I can tell you that this has by far been the most challenging replacement I have ever done.

There are two hurdles to overcome. First is that the MacBook card is shorter, second is that the uFL connector from the antennas are slightly shorter than the connection on the new board, so I had to really jerry-rig it in there with a bunch of electrical tape.

I will be posting a write up sometime soon, and will update you when its done. In the meantime, go buy the card from eBay for $5 https://is.gd/PxYlLt
