Every iMac we open receives all our love. Like usual, we use the highest quality parts. We don't skimp out. When replacing the HDD with an SSD, we do everything needed to make it last. We install the SSD in a special Vibration dampening Caddy that promotes good airflow for cooling. We Install the appropriate Thermal Fan Control Sensor on the SSD so that the iMac can regulate its internal temperature correctly (not software like others use). When closing up your iMac, we even use the correct seals for the screen so that in the future, when it is time to clean out that dust, the screen is not at risk of breaking!
