    You don't.

    21 inch screen iMac are glued up, sealed up, non-user upgradeable computing "appliances", now.

    There is NOTHING inside of a 21 inch screen iMac that can be replaced by the user.

    Everything is soldered into/onto the smaller screen size iMac's logic board, now.

    If this is a brand new 21 inch screen iMac, you have 14 days to return it for a full refund and you can re-order/repurchase a new iMac with the specs you need.

    If you have had this iMac longer than 14 days, then you would need to sell this iMac yourself and use the monetary proceeds to purchase another new 21 inch screen iMac.

     

     

    FYI,

    If you are wanting to speed up this iMac by having more RAM, this will give you the ability to have more room to run more apps and to process a lot more temp data related to RAM, but won't, neccessarily, make a new 21 inch screen iMac work and perform faster.

    To get the fastest 21 inch screen iMac possible, you would need to spend the money to get a faster i5 or i7 CPU, AND forget a straight up standard, conventional spinning hard drive and opt either for the Fusion Drive option OR the much better option of a full SSD for getting the most speed and "future proofing" of a 21 inch screen iMac model.

    The smaller screen iMacs use slower, laptop grade/style 5400 RPM hard drives (even in the Fusion drive options, as well), now which are 33% slower spinning drives than when Apple used to install the industry standard, desktop grade 7200 RPM drives into the 21 inch screen model back before 2012.

    So the slower spinning hard drives may be another point of slower, overall iMac performance.

     

     

    Good Luck!
