The iMac G3. This was a great computer for the time, and had plenty of features.
-
-
-
Start by flipping the iMac upside-down. It may help to lay it on a towel, so you don't damage the screen, or scratch the face.
-
-
-
Remove this Phillips screw.
-
Using a flathead screwdriver, work your way around the bottom cover, until it comes off.
-
Then, lift the bottom cover up and out, and set it aside.
-
-
-
Now, remove the DB-15 Video connector from the logic board.
-
It may be helpful to use a Phillips screwdriver to remove the thumbscrews.
-
-
-
Remove the front panel connector. (You may also need to remove an additional screw that connects the front panel connector to the logic board assembly).
-
-
-
Now, remove these Phillips screws.
-
Now, grab the logic board assembly by the piece of plastic, and lift it out.
I also recommend users pay attention to how the cables are threaded around the logic board assembly so they can re-thread them the same way when re-inserting the board assembly.

The logic board assembly. This is the heart of the computer, it contains the motherboard, CPU, RAM, V-RAM, PRAM battery, the hard drive, and the optical drive.
-
-
-
The optical drive is located near the front of the assembly.
-
-
-
To remove the drive, push it in, lift up, and then pull forward.
-
As you pull the drive forward, disconnect the ribbon cable and set it aside.
-
-
-
Remove the two phillips #00 screws.
-
Then remove the board. This will reveal that it is a standard PATA drive.
-
Congrats, the drive is free! You can use any PATA-tray loading drive in the iMac G3 which means you can install a CDRW to burn CDs in OS9 or X(if using OSX,install that DVD writer) but, of course only original drives will match the great look of the iMac).

Start by removing these Phillips screws:
-
Now, remove all of these cables:
At this step, the right screw refused to budge. I managed to strip the you-know-what out of it trying to extract it. Every tool I tried, it only got worse. I put it aside for the night and resigned myself to buying some stubborn/rusted-screw-extracting tool the next day. One of the lessons here is rest and walk away if you get frustrated because after a moment of clarity I had a crazy idea. What if I left the screw there and tried to remove the 4 HDD screws THROUGH the holes in the drive cage?! IT WORKED!
I carefully got to all the screws, simply lifted the HDD out of the still-attached bracket, unplugged the connectors and replaced it with a spanking new 120 GB IDE drive by sticking the screwdriver head into the small holes a la the kid’s game Operation! There is NO WAY I could have done this if 1) I didn’t have a magnetic-head screwdriver (thanks iFixit!) and 2) if there wasn’t an opening at the head of the drive cage on both sides for when the screws fell loose.
Hope this helps someone. Aloha!

Now, remove the optical drive retention spring.
-
Push in on both sides, and pull towards you releasing the retention spring.
Note the orientation of the retention spring. The end towards the back should be pointing upwards.
-
-
-
Now lift the drive up, and pull it out.
If you have trouble getting the drive out, note that there are two small hooks on the underside of the drive cage keeping it in place. Get the hooks out of the holes and the drive will be freed. It can be a bit fiddly.

-
To remove the drive from the metal caddy, remove these four screws from the side of the drive.

great description, great photos
Many thanks. Worked perfectly.
is the hard disk on a mac interchangeable to iMac 4984 from iMac M5521? Power supply failed on M5521. thx
Çok güzel. Makul bir para ödemesi yapabilirim.
Thank you so much! My grandmother finally decided to throw hers away but she wanted the hard drive and I got it for her with your help!!!
Oh thats so sad. She threw away a piece of apple history :(
Any idea if I would be able to put a modern 1tb HDD into my iMac G3?
Unfortunately not. The largest drive these machines support is 128GB total but you must partition the drive so that the OS / boot partition is 8GB or smaller. If you want the machine to be faster and more reliable, you can install a 120-128GB solid state drive with an IDE-to-SATA adapter.
