I am sure many of you want a 1TB Solid State Drive in your 27" iMac (Slim Unibody), but don't want pay Apple another $900 for the privilege. Well, I have good news: you can do it yourself and save over $650! It's super-simple: I did six of these upgrades in one day.

Note: applies to all 27" iMacs 2012 & Later

Curious if anyone knows why they stopped selling the 'service wedge', their part number 'IF145-224-1'.

It looks like an awesome helper for working with the new iMac configurations, but it's gone 404 on their website.

iFixit site says they no longer sell the "foam" service wedge, but they also sell a cardboard wedge that you can use.

I saw that in one of their kits, and wasn't sure what it was. I wonder if the original was too expensive, or too much like an Apple part...

Thanks for the clarification. I'll check it out.

I used a "wedge" when I worked at an AASP, but never bought one for myself.
When I work on one of those iMacs, I just roll up a towel, or fold it into a pad, and stuff it into the area between the "foot" and the back panel. All you are needing is something that will limit the movement of the hinge. If it doesn't stay in place, I secure it with a velcro strap. It gets the job done for me.
