For our take-apart project, I disassembled an older model of Xbox controller was surprised how easy it was. After removing a few screws (including a tricky one hidden under a sticker), I found that all of the different components simply clip onto one central circuit board that contains all of the processing power for the device.
Here's a look at all of the parts in one view:
And here are the parts grouped by function:
Inputs: There are 10 buttons, 2 joysticks, and a 4-way directional button for physical inputs. There are also 2 slots for memory cards. (Not pictured is the cord which I think is also likely an input as well as an output.)
Outputs: The only outputs are a cord connecting the controller to the XBox and 2 small motors for haptic feedback.

Processing: The main processor is a chip labeled 92163/JFL on the rear side of the circuit board. The circuit board contains all of the processing hardware as well as multiple components for receiving inputs and driving outputs.
