iMac mid-2011 2.7 i5 27-inch SSD Upgrade

My Problem

After upgrading to el capitan, imac was extremely slow no matter how I tried to resolve it. Suggested to my old man "lets turn it into a rocket ship"...... and here we are.

My Fix

Smooth, took about 2 hours to do. After installing the SSD, I did a clean El capitan install on it, leaving the SSD for the OS to make it nice and snappy. The old 1TB Mechanical HDD is now just for storage :)

My Advice

Make sure you have plenty of room so you can turn the imac in the direction you feel most comfortable working! You also need a good sized flat surface to place the glass and screen down. When moving the logic board out of the way to put the SATA cable in, its best to stand the iMac up.
