Introduction
Remove the front bezel to gain access to your iMac's innards.
Tools
- 
                  
                  
- 
            
Loosen the two captive Phillips screws securing the access door to the iMac.
 - 
            
Remove the access door from the iMac.
 
 - 
            
 - 
                  
                  
- 
            
Flip your iMac over and lay it stand-side down on a flat surface.
 - 
            
To lift the front bezel off the iMac, simultaneously:
 - 
            
Use your thumbs to press in the RAM arms and hold the iMac down.
 - 
            
Use your index fingers to pull the small bridge of material on the front bezel toward yourself.
 - 
            
Pull the Front bezel up with your index fingers.
 - 
            
Once the small bridge of material has cleared the RAM arms, lift the front bezel by its lower edge just enough to clear the bottom edge of the rear case.
 
 - 
            
 - 
                  
                  
- 
            
Insert a plastic card up into the corner of the air vent slot near the top of the rear case.
 - 
            
Push the card toward the top of the iMac to release the front bezel latch.
 - 
            
Pull the front bezel away from the rear case.
 - 
            
Repeat this process for the other side of the front bezel.
 - 
            
If the bezel refuses to release, try pressing the lower edge back onto the rear case and repeat this opening process.
 
 - 
            
 - 
                  
                  
- 
            
Lay your iMac stand-side down on a table.
 - 
            
Lift the front bezel from its lower edge and rotate it away from the rest of your iMac, minding the RAM arms that may get caught.
 - 
            
Lay the front bezel above the rest of the iMac.
 
 - 
            
 - 
                  
                  
- 
            
If necessary, remove the piece of kapton tape(it is ok to toss this) wrapped around the microphone and camera cables.
 
 - 
            
 
To reassemble your device, follow these instructions in reverse order.
That is a really, really unnecessarily complex way of fitting a new hard drive. Thanks, but no thanks...

I found this guide to be very useful. The installation was super easy, especially since I've never opened my iMac before. I was able to skip steps 6, 7, 9, 10 and 14. Wish I had one of those long skinny magnetic torx screwdriver's though. I had to use duct tape to hold the screws on the end of the bit for step 12.
I used this opportunity to vacuum out the dust with mini attachments. Much needed after 3 years ;0)
Awesome site!!! Thanks for sharing your knowledge and saving me time and $$$!
