iMac Intel 21.5" Retina 4K Display 2017 Repairability Score: 3 out of 10 (10 is easiest to repair)
Final Thoughts
  • iMac Intel 21.5" Retina 4K Display 2017 Repairability Score: 3 out of 10 (10 is easiest to repair)

  • The CPU and RAM—two of the components you are most likely to upgrade at some point—are both modular.

  • The standard 2.5" SATA hard drive is fully upgradable—though you can't add a blade SSD thanks to an empty pad on the logic board.

  • Cutting the tape to open the iMac isn't too hard (with the right tools), but it must then be replaced to complete any repair.

  • Most replaceable components (like the RAM) are buried behind the logic board, meaning you'll have to take apart most of the iMac just to gain access to them.

  • The glass and Retina Display are fused together, increasing the cost of replacement.

iMac Intel 配有 21.5" Retina 4K 显示器(2017版)的可维修性得分:3分(10分为最高分,表示最易修复)

最有可能替换的CPU 和内存皆为模块化,便于日后升级。

标准2.5寸 SATA 硬盘完全可升级,但是您不可以利用逻辑板上的空处加装刀片式 SSD。

切开连接带来开启 iMac (使用恰当的工具时)并非困难。但是每维修一次,你都需要更换新的连接带(因为你必须切断连接带才能打开 iMac)。

最有可能更换的组件(比方说内存)都藏在逻辑板的后部,这意味着你必须将 iMac 大卸八块才能替换他们。

玻璃面板和 Retina 显示器被熔接在一起,徒增了维修成本。
