Teardown of New Mac Pro Reveals Surprising Amount of Accessibility, Circular Daughterboard
The new Mac Pro includes a rear lock switch that allows the device's cylindrical casing to be removed with ease, allowing the user to easily access and replace components such as memory modules, SSD drives, and more. A teardown performed by Other World Computing (OWC) earlier this week also revealed that the Mac Pro includes a removable CPU, which may be useful to users who want to upgrade their machines in the future. Non-proprietary Torx screws are also found throughout some parts of the machine as well, which makes for easier repair.
Another internal to note in the Mac Pro is its power supply, which appears to be located in between the I/O panel and the logic board. The power supply itself appears to be rated at 450 Watts, and relies solely on Apple's highly touted single fan cooling system in the Mac Pro to keep a low temperature. This, in unison with the triangular heat sink that cools the graphics card and GPU, allows the Mac Pro to idle at a quiet 12 dBA.
Furthermore, the logic board, dual graphics cards, and I/O port board found on the machine appear to connect to a single daughterboard, or interconnect board, found at the base of the machine. However, unlike the other parts of the computer, the daughterboard appears to use a tight cable routing system and various new proprietary connectors.
As is tradition for iFixit's teardowns, the company has assigned a repairability score to the 2013 Mac Pro based on the accessibility of the various components. While iFixit disliked the inability to add additional internal storage and the tight cable routing system in some places, the new Mac Pro's repairability scored a high 8 out of 10, with the firm crediting the computer for having non-proprietary Torx screws, an easily accessible case, and a user replaceable CPU.
