Thank you - the top left of my screen actually has a small chip, maybe 1/4 of an inch - doesn't affect anything and is only on the black border trim, do you think I may have an issue with that when removing?Yes, I've done it a couple of times now and there's some really good videos out there which will help you - watch them a few times before you start and watch them again while doing the upgrade, step by step. If you have a decent toolkit like the iFixit one, you just need some patience and a nice big, clean working area.
Like @TwoH says, the heatsink mechanism they use can be a bit daunting due to the force you need to maintain on the brackets to screw them down, but I wouldn't let that put you off.
Personally, I found getting the board out to be a bit fiddly - I think its the SD card slot which makes it a bit of a pain. The only thing that I will always be nervous about are the edges to the screen which seem precariously thin, so just need to be careful when taking it on/off.

Only thing I am worried about are the 3 cable connections to the screen, those are fairly easy to get on and off right?No, I’m sure it will be fine. Just take care when putting the screen on/off not to be putting the surround of the screen under pressure by resting it against the iMac if that makes sense? The outermost surround of the screen seems very thin so could easily crack I think if you put it under pressure.
Just saw this thread. Upgraded my stock 8-core to 18 core (bought in China via e-bay for about $600) and upgraded RAM to 128 GB. Took a long time. Everything works well.Have an 18 core Xeon and more ram coming, with extra adhesives. Anyone attempted this on iMac Pro? Tips?
