Taking apart an iMac

To the interesting thing for today is taking apart an iMac. I needed to do this today because one of the computers for a secretary only has a couple hours at most left of life. So I need to get it out and into another computer where I can do a Live CD/USB and try to save all important data off of it while it can still spin. Here is the link I found that shows just what I need to do to take it apart. http://www.powerbookmedic.com/manual.php?id=97. It showed just what I need to do and all I can do today is take out the memory and take off the glass. I need to go get some T-6 and T-8 bits tonight to finish taking the computer apart. Also when I have those bits, I should be able to dismantel HDD's that have gone bad for the fun of it and keep the platters and magnets. HDD magnets are fun and strong i think. Don't worry about the rest of the story about our VoIP system, I'll tell it soon.
