Just did this upgrade last week (July 2021). Worked a treat in my iMac7,1 2007. Successfully ran both Mojave at 10.14.6 and Catalina 10.15.7. About This Mac doesn’t show the correct speed, displays 400Mhz <grin>. Clips along nicely, everything works just fine, Bluetooth, Wifi. Thought I would smarten it up too with a new paint job, so it didn’t look so dated.

Hello Ronan

Hello @ronan0s
Sorry for the delay in replying
I used PlastiKote Metallic Blue for the paint. I disassembled the iMac including removing the stand, so that I could make a proper job of spraying it.

I realised that the tiny microphone hole matrix at the top of the display would get clogged by the paint, so after removing the microphone I replaced those tiny holes by drilling a single hole about 2mm diameter.

I wanted to spray the black iMac logo independently so with the help of isopropyl alcohol I managed to remove that and sprayed it matt white.

For the keyboard I popped off all of the key caps, and put tape in their place to protect them from the paint. With the mouse, I masked off the aluminium body pretty easily using the gap between plastic and metal.

I decided not to spray the memory door, as it was already going to be a tight fit to replace after getting a bit of overspray.

Now I just need to decide what colour to use for the next one :-)
