Neither. It is simply a container for the more fragile components.
input & output
out put
A joystick is an input device. It receives input from the user in the form of it's operation which it then passes on to the computer. Speakers are an example of an output device. They receive no input from the user, and only output (sound in this case). You can think of an input device as something that gives the computer information. And an output device as something that receives information from the computer.
A computer case by itself is not a peripheral as such, nor is it an input or output device. It is just the cabinet that contains the computer system. That said, the components inside fill all of those roles. The case contains the motherboard which is about output, input, and processing.
A printer is an output device... UNLESS it's an 'all-in-one' in which case it's an input device too !
In computing, a case refers to the physical housing or enclosure that contains the components of a computer or electronic device. As such, a case is typically considered an input/output device because it provides access to the internal components of the device, allowing users to interact with them. Input/output devices are devices that allow users to input information into a computer or electronic device, or receive output from the device. Examples of input devices include keyboards, mice, and touchscreens, while examples of output devices include monitors, speakers, and printers. While the case of a computer or electronic device is not directly involved in the processing or transmission of data, it is essential for protecting the internal components and providing access to them. Without a case, the internal components of a device would be exposed to dust, moisture, and other hazards, and it would be difficult or impossible to access and repair them.
The output of a computer can be purely visual, in which case the output device is a monitor, or it can be printed, in which case the output device is a printer; when computers produce sound, the output device is a speaker.
Yes a microphone is an input device. Input/output devices are determined by the direction of the signal being transfered. If the signal is being sent to the Case (main part of the computer that does all the work) then the device is classified as an input device and vice versa. Since the signal from the microphone is sent to the Case, the microphone is "inputting" information into the computer.
In the strictest sense, no. It is an output device only. However, touch screens are input devices, but some would say this is just the touch panel mounted on top of the screen - so the screen is an output device while the touch panel is a separate input device. They are integrated into one unit but do have separate connection to the computer. Some would say its it one unit that does both input and output since the touch panel is integrated. The case could be made for either really, its just semantics anyway. Also, some monitors have USB hubs built in, but these really just bridge the USB device and the USB controller in the PC with no actual processing of data, so really shouldn't be considered an input device either.
It's an output device - UNLESS - it's a printer/scanner - in which case... it's both !

Scanners can only be used as an input device. They scan the image placed inside/ontop and digitalise it and display it on your computer screen. The only type of scanner that can output is an "all-in-one" scanner/printer that can print out the images you scan in or other images from your PC, but that is not technically a scanner, it is a scanner, printer combination. So no, Scanners can only be used as input devices.
No, an input device is something that carries data into something. In this case, the processor. This incoming information doesn't have to be analog information coming from a human, but it sometimes is. (E.G. a computer mouse, a computer keyboard) It also could be another electronic device interacting with the computer. (E.G. a flash drive, a phone, an mp3 player). For a better way of understanding this, here is how input and output work: Input -> Processor -> Output Keyboard -> Computer -> Monitor
A case (desktop?) computer is an input (receives data from keyboard), output (displays data on a monitor or sends to a printer), and storage (when data is stored on a hard-drive).
