    Is it possible to replace the RAM and Graphics Chip in a 20" Intel iMac?
    Hi,

    Is it possible to replace the RAM in a 20" iMac (ie, 2 x 512mb to 2 x 1gb) and the Graphics Chip (ie, 128mb to 256mb)? I heard its quite hard to get inside the intel iMacs. Any help is appreciated.

    Thanks,

    I don't have an imac but appl has step by step instructions online.

    Remember google is your friend.

    Graphics chip is another story. Getting into the imac isn't too dificult. I've seen step by step instructions on how to replace the imac hard drive. But the graphics chip is pretty much built into the logic board. Remember they are bascially laptops with detachable mice and keyboards.

    Nope, they are desktop computers in a small case.

    Anyway wytwolf was correct, there is a slot under the display is easy go get to and from there you can up your RAM. The graphics card is removable in the 24" iMac... I'm not sure about the 20. But when you buy your iMac online you have the option to up your video card so just do it there and you're good to go.

    Have built multiple systems over last 4 years, all with parts from newegg.
    Their service has always been very good and pricing is typically at or close to the best you can find.

    The RAM is the only thing you can service without voiding your waranty. And it's the only thing made easy enough that it shouldn't really go wrong, provided you get the proper modules.

    No, they are closer to laptops precisely because the components are not detachable or replaceable. The iMac and Power Macs are very different - the latter has a motherboard with PCI and PCI-Express slots.

    iMacs and Mac Minis are custom made in order to squeeze into a small case, regardless of the shape. Much closer to laptops in design.

    It doesn't matter how small the case is or how accessible it is, the iMac still uses desktop components.
