A complete teardown of the recently released Mac Mini revealed that the 2014 model is tougher to repair than the 2012 model. The 2012 Mac mini received a score of 8 out of 10 based on repairability but the latest model received two points less due to the inability to upgrade the RAM of the device.
The CPU is soldered to the logic board which means that the RAM can be increased only during the time of purchase. The new Mac mini has introduced three TR6 Torx Security key fixtures that require bespoke tools to remove it and makes the process of cleaning the fan or hard drive a tough task.
“This is the smallest Torx Security screw we’ve ever seen – our kits go down to T7 security,” said the team.
The hardware includes a 1.4GHz Dual-core Intel i5 processor, 4GB of 1600MHz LPDDR3 memory, 500GB hard drive, Intel HD graphics 5000, Wi–fi and Bluetooth 4.0. The backside of the Mac mini is similar to earlier models, except that it carries two Thunderbolt 2 ports instead of a FireWire port.
After removal of the Wi-Fi cable and the fan screwed to the logic board the AirPort card with the IC’s are revealed. The card consists of Broadcom 5G Wifi 3-stream Gigabit Transceiver, Skyworks, Dual-mode WLAN front-end module, RF Micro 2.5GHz FEMS and Broadcom single-chip Bluetooth 4.0 HCL support with Bluetooth low energy support.
The logic board consists of Samsung 8GB LPDDR3 DRAM, Cirrus logic Audio Codec, Broadcom Ethernet PCLe controller, Intel Thunderbolt 2 controller, Delta Electronics LAN filter and NXP 9-bit I/O expander. Other components include SMbus temperature sensor, Cypress semiconductor, DDR3 Memory Power Synchronous Buck controller and NexFET Power Block from Texas instruments. The power supply is easily extracted and the hard drive tray supports the 500GB hard disk.
No glue was found during the simple disassembly of the Mac mini though the CPU and RAM has been soldered which gave the device a repairabilty score of 6 out of 10.
