• iMac Intel 21.5" EMC 2428 Teardown

    I may sound silly but can you actually change/upgrade the CPU from the I5 to an I7 by yourself and, with the 27" iMac there are 4 ram slots is this the same on the 21.5" Apple originally said it only had 2 but now they say you can upgrade the 21.5" to 16GB Ram (4x4GB)? Thanks
