Speziell für diesen Teardown benötigte Werkzeuge


We picked up the new Mac mini from our local Apple store and took it apart!

    • The Mac mini for this First Look was graciously provided by our friends at macminicolo, a Mac mini colocation service. They allow your Mac mini to be used as a surprisingly powerful and inexpensive server.

    • Ladies and gentlemen, without further ado, allow us to introduce the new and improved Mac mini!

    • We immediately tried to open the mini using our iMac opening tool, used in yesterday's iMac First Look.

      • It did not work.

    • We also posted a guide for installing a second hard drive in the Mac mini.

  2. The beauty of evolution at its finest. From left to right: Power PC, Intel Core Duo, Intel Core 2 Duo.
    • The beauty of evolution at its finest. From left to right: Power PC, Intel Core Duo, Intel Core 2 Duo.

    • Notable differences in the latest model:

      • An additional USB port brings the total to five, one more than the previous model (and three more than the Power PC!).

      • A Mini DisplayPort and mini-DVI port -- which allow for Dual-Monitor support for the first time in a Mac mini -- replace the DVI display port of the previous generation.

      • A Firewire 800 port replaced the old FireWire 400 port, much to the chagrin of Mac users.

    • Let's rock this thing!

    • Carefully insert a putty knife into the crevice in between the top cover and bottom housing. Start on the left side first.

    • Gently enlarge the existing crevice by twisting the putty knife downward and away from the mini.

    • Repeat the prying motion until a portion of the bottom housing has been nudged upward.

    • Repeat the same prying procedure on the right side.

    • The top cover should now be marginally separated from the bottom housing. Use your fingers to completely separate the two, starting with the I/O side of the mini.

    • The top cover does not have any cables attaching it to the bottom housing; it should now be completely detached from the bottom.

    • A quick comparison photo of the three Mac mini generations (oldest on left) showcases their technological progression:

      • No antennas --> One antenna --> Two antennas (Airport card)

      • Desktop RAM --> laptop RAM

      • PATA --> SATA drives

    • Can you hear me now? Excellent.

    • The wireless board contains a Broadcom BCM4312KFBGH WiFi transceiver on it.

    • The new mini houses three wireless communications antennas, one for use with the built-in Bluetooth and two for the Airport Extreme wireless 802.11n card.

    • All three antennas need to be removed before accessing the hardware underneath.

    • There are two black posts securing the Airport antenna board to the internal frame.

    • Squeeze both black posts together and gently lift the antenna board from the post.

    • Rotate the mini 180 degrees.

    • Use a spudger to peel back the black tape and release the antenna cable.

    • Carefully lift the remaining two antennas from the right side of the mini.

    • Remove the four black Phillips screws holding the internal frame to the bottom housing.

    • We spent a lot of time searching for these screws. Is this an Apple conspiracy to prevent consumers from disassembling their products? Put on your tinfoil hats!

    • After the screws were removed, we separated the internal framework from the bottom housing.

    • On the left we have the bottom housing, which includes the logic board, CPU, and RAM. On the right is the internal framework, which contains the SuperDrive, fan, and hard drive.

    • Remove the six Philips screws from the left, right, and back sides of the SuperDrive.

    • Unplug the drive from the interconnect board to completely remove it from the framework.

    • Use the Mac mini Terabyte Upgrade Guide instead of this First Look to make any modifications to your mini.

    • Next, disconnect the small black two-wire connector from the interconnect board and move it out of the way.

    • Remove the four Phillips screws securing the hard drive to the internal frame.

    • The hard drive easily slides out once it is detached from the interconnect board.

    • The hard drive is a paltry 120 GB. If you'd like to hold more than six photographs on your computer, you can upgrade to a 500 GB drive for just $130 and a little time.

    • Apple only allows you to customize the mini with a 320 GB drive, and they want a whopping $175!

    • Remove the two screws holding the fan in place.

    • Disconnect the fan's blue/gray cable from the interconnect board. This should allow the fan to be removed from the framework.

    • The top half of the Mac mini is now completely disassembled!

    • Now for the lower half...

    • The standard quick pry with the fingers (and subsequent pull) frees the RAM from the logic board.

    • Our $599 mini shipped with only a single 1 GB PC3-8500 chip. In this configuration, the NVIDIA 9400M graphics processor allocated 128 MB of this memory as VRAM. When we installed a second chip in this machine, for a total of 2 GB, the 9400M automatically allocated 256 MB VRAM instead.

    • On to the AirPort/Bluetooth board removal. A couple of steps are needed to remove the board:

      • Disconnect the three antennas (marked in red).

      • Disconnect the AirPort/Bluetooth communication cable (second photo).

      • Remove three Phillips screws (third photo) and then completely remove the AirPort/Bluetooth board.

    • Once we had removed the AirPort/Bluetooth board, the only thing preventing us from taking out the logic board was two connectors and a T10 Torx screw.

    • Disconnect the power button cable and the power-on LED.

    • Use a T10 Torx screwdriver to remove the standoff screw.

    • Use a spudger to gently pry up the logic board.

    • Grasp the logic board with your hand and pull it away from the I/O ports.

    • Voila! The logic board is free.

You guys rock. I always find this so interesting. Thank you!!!

just what I was hoping to see

Very nice presentation, with excellent photos.

Is the CPU a standard pin configuration? If so one should be able to desolder it and either fit a socket or solder in a upgrade.

Does anybody have boardview schematics for this specific model? Revision C. I can only find Rev A boards online and even then they’re not full board views. My Mini is having some bad logic board problems (fans spin up to max speed immediately upon plugging in, no power button required), diagnostic LEDs don’t turn on, and other than the fan it’s the only sign of life it has. The Mini will just sit there for however long on full speed fans unless I unplug the machine, no display, and unresponsive to me either pressing the power button or jumping the pins. If I’m lucky I can leave it sit for a couple hours, unplug it and replug it a few times, switch a RAM stick to the other slot or some other obscure fix, and then get the diagnostic LED to turn back on but the Mini just panics upon starting and won’t get into OS X. After it panics it’ll reboot and the diagnostic LEDs are gone again, and it’s back to the fan turning itself on and not turning off. lts really hit and miss at this point and unless my one wire circuit is destroyed I’m not sure why my fan is being turned on by ghosts. I’ve gotten the device to boot with my RAM (6GB DDR3) so I don’t think that’s the issue but I’m leaning towards the idea it’s a bad SMC. Of course that’s not a super easy repair so a schematic or board view would help a bunch. If anyone else has dealt with any similar problems I’d appreciate some insight!
