Let's start with the computer case. This is the metal enclosure that contains many of the other hardware components. It comes in various shapes and sizes, but a typical tower model is between 15-25 inches high. Want to know what's inside? Okay, go get a screwdriver and let's open it up. Seriously, if you are really into computers, the best way to learn is to actually get hands-on. To save us some time, however, have a look at this desktop computer case. A computer enthusiast replaced the metal side panel with a transparent one, so we can have a look inside.

Although that photo looks pretty cool, it is a bit hard to recognize the individual components, especially.with all the connecting wires running through it. This figure shows a more schematic version of a desktop computer, which makes it easier to point out the essential hardware components.
The various components of a computer case
computer tower schematic.The computer case contains a power supply unit to convert general-purpose electricity to direct current for the other components. The most critical component is the motherboard a plastic board on which several essential components are mounted. This includes the central processing unit, or CPU, the main memory and expansions slots for other hardware components. The internal hard disk drive serves as the mass storage device for data files and software applications. An optical disk drive makes it possible to read from and write CDs and DVDs. Other hardware components typically found inside the computer case (but not shown in the figure) are a sound card, a video card, and a cooling mechanism, such as a fan.
We made this list based on our own opinion, research, and customer reviews. We’ve considered their quality, features, and values when narrowing down the best choices possible. If you want more information and updated pricing on the products mentioned, be sure to check the links in the description box below. So, here are the top five Best Entry-Level Mirrorless Cameras. The fifth product on our list is the Fujifilm X-T200. X-T200 is Fujifilm’s upgraded version of their somewhat lackluster X-T100. It uses the same APS-C CMOS image sensor, but it is made of copper wiring rather than aluminum. It allows the camera to have a 3.5x faster readout and a maximum ISO value of up to 25,600. The processor is also upgraded to provide the device up to 8fps continuous shooting speed. Its 4K video capture can go up to 30fps – a massive improvement from X-T100’s 15fps. Its Full HD 1080p video capture is now up to 120fps too. Moreover, X-T200 has an HDR video mode that provides more dynamic range to standard videos. To help you capture smooth footage, Fujifilm gave this device a digital gimbal that you can use to take Full HD videos. You can also trim your footage in-camera. Another notable feature of X-T200 is its 3.5-inch 16:9 rear LCD. It comes with a high-resolution panel of 2.76 million dots, suitable for smartphone photographers transitioning to real cameras. For its autofocus system, X-T200 has a hybrid autofocus system with 425 sensor-based phase-detection points. It has four autofocus modes – Single Point, Zone, Wide/Tracking, and All – to help you keep things in focus. The face detection is also spot on. The Fujifilm X-T200 produces images with excellent color reproduction, good dynamic range, and acceptable noise performance. They are clear and detailed. But, at the same time, they look very natural. Its pros are: - It produces images with excellent color and dynamic range; - It is designed with a sharp 3.5-inch rear touchscreen; - It has a reliable autofocus performance; and - The sleek retro design is conveniently lightweight. However, the cons are, - The camera has a low buffer depth; - It does not have subject tracking in videos; - Its eye sensor can be unreliable at times; and - The joystick is not placed well when using the viewfinder. The Fujifilm X-T200 is a good choice of a beginners’ mirrorless camera thanks to its autofocus performance, video capture features, and speed. So it is a device worth considering if you are thinking of upping your photography game from smartphones and point-and-shoot cameras. Up next in the fourth place is the Nikon Z50. Part of the Nikon’s Z series, Z50 is the brand’s entry to the saturated APS-C mirrorless market. It comes with a 20.9-megapixel sensor and an Expeed 6 processor that facilitates other features in the camera like the 4K video capture and native ISO range. Using the same hybrid autofocus system as its predecessor Z6, Z50 has 209 on-sensor autofocus points covering around 90% of the frame and delivering edge-to-edge sharpness. You can also have sensitivity down to - 4EV for low-light shooting and eye-detection autofocus for photographing people. Z50 allows you to choose between an electronic viewfinder, and a TFT LCD to compose your images. And because shooting 4K video is almost a standard now, you can expect that Z50 can allow you to do this with frame rates up to 30fps. Technically, this model has a smaller sensor and lower resolution than other Nikon cameras. However, that does not stop Z50 from producing images with a lot of detail. They boast of great color and look realistic, even with a fair amount of vibrancy and saturation. Physically, Z50 is like a miniature version of its bigger siblings Z6 and Z7. They have the same layout, viewfinder placement, and button layout. One big difference is Z50 comes in a more compact frame, and to save space, Nikon removed some controls and resized the buttons. It also has a nice grip, so you will not feel uncomfortable despite using the camera for a long time. Its pros are: - It gives good value for the money; - It is built with a nice viewfinder and screen; - It uses SD
