We completely disassembled an Apple Mac desktop computer into its component parts. During this process, we observed and analyzed the methods of assembly, the integrated electrical design, materials used, and utilization of different tools.
In terms of the methods of assembly, this particular desktop computer was seemingly not meant to be opened up and disassembled, based on how difficult it was to remove the outer frame, unscrew each component, and pull apart strongly adhered bits. Initially, we were very confused about how to remove the case. Another team disassembled a similar computer and was lucky enough to have some cracks on the outside which helped them remove the case. However, we had to open the device through a slot in the bottom where the RAM was located. To do this, we used a torx screwdriver to open the case which comprised a front and back frame. Once we opened it, a system of wires, plastic and foam adhesive, tape, and screws made it all the more difficult to disassemble. We approached it systematically with intense perseverance and eventually made our way past the LCD screen.
We separated the various components that contributed to the overall functioning of the computer; immediately, we identified the fans, speakers, hard drive, disk drive, power supply, power inlet, RAM, front camera, stand connection, and mother board. The electrical components were connected through an intelligently designed system of wires through micro USB ports. The mechanical components and electrical components were connected through a system that snapped them into place into a large inner metal frame, glued them down, taped them together, and screwed them in.
Our most important tools were the torx and phillips head screw drivers. By the end of the disassembly, we had around 70 tiny screws, discounting the ones that we inevitably lost. We also used a larger flathead screwdriver to pry apart some of the more stubborn attachments. For the majority of the project, however, we were using our hands to disassemble different components. For example, one of the more intelligently designed methods to keep things together was a snap-in system, where a frame connected to other components through slots. This had to be pried apart with our hands.
In conclusion, we were impressed by the variety of materials and methods of assembly. For how complex the components were, there was a surprising level of simplicity for attaching them together. We enjoyed learning about how things fit together, and seeing novel and not-so-novel methods of assembly.
