The best part of the iFixit teardowns — besides the gadget pr0n — are the notes found on the last step. iFixit grades the given product in terms of its repairability and then comments on the highlights. The new iMac scored 7 out of 10 where 10 is the easiest to repair. iFixit notes that while it’s relatively easy to disassemble the iMac, “Making the LCD and glass spotless when reassembling the machine is nearly impossible.” But at least you can replace the RAM, hard drive and optical drive with “relative ease.”
