8th generation Intel Core i3 quad-core processor clocked at 3.6GHz

8GB of DDR4 RAM Running at a speed of 2400MHz

A mediocre 1 TB mechanical hard disk drive.

AMD Radeon Pro 555X graphics card with 2GB of GDDR5 video RAM.

And of course the gorgeous 4K Retina Display with support for the P3 color gamut.

Opening the iMac has never been easier with ifixit opening tool.

I did use these 6 tools

It was really disappointing to see nothing is changed in this iMac in last 2 years.

it seems they have changed the LCD connecters only

The large LCD screen is made by LG Display.

Only wifi and bluetooth module in now fixed on the board. Hard drive still same Hitachi 5400 rpm and fan still the same as you can see

A protection cover for the RAMs which I think is not necessary for a fixed device like this and as you know 2666 MHz DDR4 rams are little higher speed than the 2017 model.

Insert wisdom here.

Power supply

If not handled correctly, the power supply can do bodily harm.
