Got a new iMac for the fam and just wanted to future proof it/ make sure it stayed useable despite the detritus that 4 people leave on a computer.
Glass cover piped out way easier than I had anticipated and the rest if the disassembly was a breeze because of the awesome tools in the set. The crucial m4 I got didn't come with brackets to make it fit in a 3.5 inch drive slot. No worries tape to the rescue. Putting things back was interesting because of the magnets in the LCD but put it altogether at a much lower cost than paying for the upgrade through apple!
Pull the glass off from the top. Metal brackets on the bottom can get bent if you're not careful!
