If your hard drive fails in a new iMac, Apple has a new way of "holding' their screens in - double sided tape. Gone is nice mechanical fasteners such as screws and the magnets.
Naturally you have one shot of pulling OUT the screen but the glue won't let you replace it. Get those from an Apple Store "No sir, you MUST BRING IT IN FOR REPAIR". A $70 hard drive ends up being $250 from Apple here in Australia. If you want to do it yourself Apple refuse to sell you the screen sealing tape to hold the lot back together - regardless if it was out-of-warranty.
It was sure nice to see iFixit has the sealing tape to fit.
I'm ready to go - just haven't done it yet but I have the tools, fixing and instructions.
Make sure you know what model iMac you have BEFORE opening it - finding out that you need special tools, fixing tapes etc. AFTER you open it will only delay your repair.
Review those great "fix it yourself' iFix-It, then get to work.
