1New Apple iMac Family
iFixit purchased a 21.5-inch model for its teardown, affixed two heavy-duty orange suction cups to its LED-backlit glossy widescreen TFT (thin-film transistor) display and separated the glass panel from the front bezel. iFixit then removed several Torx screws and lifted the LED display to reveal the iMac’s innards.
4Break Out the Soldering Iron
In hardcore fashion, the teardown team removed the Bluetooth board, secured it in a special vise and desoldered the shield to reveal the “chip goodies” hiding underneath. These included a Broadcom Bluetooth IC and a multipurpose flash chip that was the same as the one they found in the first MacBook Air.
In conclusion, iFixit reported, the iMac’s front glass panel and LCD are easy to remove; the RAM, hard drive and optical drive can be replaced with “relative ease”; the CPU and GPU are possible, though not easy, to replace; while getting out the logic board is a downright pain.??Ã (Image courtesy of Apple.)
