Hard drive replacement and memory upgrade
The 320GB internal hard drive on my 24" iMac Intel died. I replaced it with a 1TB drive and, while at it, maxed out the RAM to 4GB. I used the 20" iMac repair guide which was very close. It is not the first time I used iFixit guides. I also fixed an old MacBook a few years back. I love you guys!
It went peachy. Everything worked beautifully when I was done.
Follow the instructions on the repair guide and all will be fine
