I finally did it!!!
Installed the Corsair F60 GB SSD in my 7.1 2.4Ghz iMac.
It took me about 3-4 hours (I was being too careful) but i have to say that installing an SSD is totally worth it.
After installing most of the apps that I normally work with I still have 40GB space free... Yay
Applications are opening up in just one bounce...
If anyone else want to do the same here are the things you should keep in mind.
* I had to use about 4 different sizes of Torx Screwdrivers and 1 very small Allen key to remove all the screws.
* If you want to install the SSD you should get yourself a bracket, just to hold the SSD in place. A metal bracket will do. Corsair F60 SSD comes with one so I was good to go.
*
iFixit has a good teardown guide and you'll get some videos on youtube too, they are a good place to start but you should not depend on them and see for yourself how it is assembled and how a cable can be detached and placed back. There are slight differences in every model of iMac.
* Even the smallest of Suction cups will do, even if you have only one, I used the one which came with my Spyder3Pro monitor calibrator. I placed it on the right upper corner and pulled the glass gently, held it in position, removed the suction cup and placed it on the bottom left corner, pulled it and I had the whole glass in my hands. It was really easy.
* Remove the cover of RAM slots which is screwed at the bottom of the iMac.
* Remove all the screws. Remember their positions, it'll help to lay them on the table as you removed them.
* A temperature sensor is attached to the HDD, be careful while detaching it and note down how its attached.
* While detaching the LCD from the main frame there was a cable, looked like graphics card cable, which was a bit difficult to detach as its socket was very tight, but I successfully detached it by seeing carefully that it can be detached and then pulling it hard enough.
* The HDD was had four screws, 2 of them were removable. Look for the ones which are easily removable and unscrew them first.
* Put the SSD in place and you are ready to assemble the iMac and go.
* I turned the iMac on and checked that its working before putting any screws back.
Hope it helps
Thanks
