MacBook to a Mac Pro Ultra mini?

I quickly saw the motherboard wasn’t going to fit without cutting off the bottom of the HD case.  I did see that the case would be tall enough with the legs to house the motherboard.  I also measured for thickness to see if  the notebook hard drive would fit once the motherboard was mounted.  Next I cut parts off of the inner hard drive mount so that all ports would be accessible from behind.  After a few extra cuts and grindings I was ready to attach the motherboard.

Looking at the old Macbook case all the motherboard support mounts were molded into the plastic case.  I decided to reuse some of the plastic, removed all of the metal frame, and cut it down to size. Next I placed small holes in the plastic near the hard drive mount holes on the external hard drive mount frame.  I then zip-tied the old case to the frame.   I was going glue or screw it in place but this gave me some adjustment room if needed.  You can see the cut case and frame below.

You can see the first dry fit below

Next came cooling.  I placed 3  1/2″ holes on the top for the cooling fan.  I placed the metal on a wood box to support it while drilling with the drill press.

Carefully removing the ribbon connection under the track pad and then removing the extra pins,  I soldered the red lead to the 4th pin.  I then scraped off some of the protection coating and soldered the black wire to the ribbon’s ground wire.  I did not connect the green wire which powers the blue LED built into the power button. The LED is much too bright when the lights are out in my living room.

After covering the connections with a hot glue gun I did several tests insuring  a good connection and that no short-circuits were occurring on the other pins. Side note:  I solder about as well as I weld, both are not pretty but they hold

Next step was to mount the hard Drive.   The original configuration used a long cable for the SATA connection so I had some options.  My first thought was about heat so I did not want to mount it above the cooling fan.   Looking at the old case the hard drive is stored inside a metal frame.  Removing  just the “cage” I made a few holes in it.  I used longer screws in one of the CPU heat-sink and the wifi card.    I added some hot glue to the bottom where any contact might be made to prevent shorting.  This still allowed the unit to slide into its  housing while providing a strong mounting spot.   I ran before and after temperature tests using Hardware Montior and found the new configuration runs just a few degrees hotter.

 You can also see I mounted the magnetic power connection on top of the Ethernet port.  I also temporarily added electrical tape to the top of the ram and board to keep down the chance of electrostatic sparking from the desk.  The working right speaker & “sub woofer” are also mounted up front.   The IR and white LED where damaged by the water.

Last I slid it back into the outer case and put a small bar with a screen on it in the center of the back of the case to keep the outer and inner case parts from moving.    That was it!  I now have a Ultra Mini Mac Pro.   I’ve watched a few HD Movies and did some stress test to make sure it would not over heat and all is well.    After a  week or so I’m going to take the out case down to the local high school and use the laser etcher to place an Apple logo on the side.   I will post the finished photos here along with more shots of the finished case.
