Hi guys, I decided to post this up to share the information focusing on put in the SSD as a secondary drive the proper factory way! First, you need: right angle SATA cable, DC harness that will give you 2 SATA power connector, and the optical drive pressure wall that consists of that magical 2.5 mounting holes! Then the disassembly begin, I am not going to re-post all those steps, you can find them ifixit and the forum here, basically: remove ram door, remove all rams, use a suction cup to take out the glass, 4x T10 screws on each side of the LCD, separate the screen from the top, start removing the top cable connection, then the lcd temp sensor, the LVDS cable, and the power cable to the LCD inverter, then remove the IR sensor from bottom, remove all connections from the logic board, and slide out the logic board Now, the differences are here, undo 2x T10 screw on each side of airport card board then remove the DC harness, 1 on the power supply and 1 on the LCD inverter, 1 from the hard drive, for the LCD inverter, unscrew 2 top screws in order to undo the clip. pressure wall with the 4 holes! you are required to remove the optical drive, 4 screws on each corners Install with 4 standard hard drive screws at the bottom Remove 1 T10 screw from the pressure wall, then just pull it with gentle force (some adhesive on the pressure wall to the back of the computer) put the screw back in the pressure wall, install optical drive, install the 2 screws from the LCD inverter...etc. Hope this would clear those struggle with using SATA spilt and velcro/strap. by the way, I live in Vancouver Canada and been an apple tech for couple years, PM me if you want to to the same to your mac!
