    • Apple has surprised us all by unveiling some new iMacs without a Keynote.

    • But what has surprised us most by far are the big specs this little iMac packs.

    • 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.

    • 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.

Hi Mohammad:

It is possible to make it 32 GB but you need to be a little gentle when doing that. feel free to ask me here if you face any issue. I actully made a video for the first time doing it you can have look at it to get some idea.
