SSD for iMac (256GB SATA III vertex 4)
1 - 4 horas
Wanted faster HDD - needed the correct cable.
iFixit had the solution. Arrived by UPS no problems.
I do this for living so was quite easy for me. The magnetic project matt helped me group all the screws together.
Use a good desk lamp to see what you are doing and remember to get ESD strap and anti static mat to work on. Use scotch tape to group the cables together, so they don't fall down inside when removing the main board.
