What’s Inside the Pc Case? Computer Components
Inside the system unit, there are several computer components that work together to form the foundation of the computer’s processing power.
One of the primary components inside the system unit is the motherboard, which acts as the main circuit board that connects all the other computer components. The motherboard contains the CPU socket, RAM slots, and expansion slots for additional cards such as graphics or sound cards.
The CPU, or central processing unit, is the brain of the computer and is responsible for executing instructions and processing data. The CPU is typically mounted onto the motherboard and sits below a heat sink and rgb fans to keep it cool.
RAM, or random access memory, is the temporary storage that the computer uses to execute programs and store data while it is in use. The RAM slots are located on the motherboard, and the amount of RAM a computer has can affect its overall performance.
The hard drive is another critical component found inside the system unit. It is used to permanently store data and programs and is typically connected to the motherboard via a SATA cable. Cases comes with multiple internal drive bays that can be used for upgrading storage.
The power supply unit, or PSU, is responsible for providing power to all of the computer components inside the system unit. The Power supply is typically located at the back of the case and is connected to the motherboard and other computer hardware component with cables.
External bays are an integral part of computer cases that allow users to add or switch out various hardware components without opening up the case. These bays are located on the exterior of the computer case and can be accessed easily by the user.
Other hardware components can also be found inside the system unit, such as the graphics card, sound card, optical drives, and cooling fans. These computer components work together to ensure that the computer system unit functions correctly and provides the necessary power and performance for the user.
Computer Cases Form Factors :
Form factors are the physical dimensions and layout of a computer case. Different form factors are designed to accommodate different types and sizes of motherboards, power supplies, and other internal components. Here are some common form factors of computer cases:
1. ATX (Advanced Technology eXtended): This is the most common form factor for desktop computers. It measures 305mm x 244mm and provides space for up to seven expansion slots.
2. Micro-ATX: This smaller form factor measures 244mm x 244mm and is designed to fit in more compact cases. It typically has four expansion slots.
3. Mini-ITX: This is the smallest form factor and measures only 170mm x 170mm. It is designed for compact and low-power systems, such as home theater PCs.
4. E-ATX (Extended ATX): This larger form factor measures 305mm x 330mm and can accommodate up to nine expansion slots. It is designed for high-end gaming and workstation systems.
5. BTX (Balanced Technology eXtended): This form factor was developed by Intel as a replacement for ATX, but it never gained widespread adoption. It features a rotated motherboard, which improves air flow and reduces heat buildup.
Overall, choosing the right form factor for your computer case model is important in ensuring that all the components fit properly and that your system runs smoothly.
Types Of PC Cases
The types of computer cases can be broadly categorized into two main groups: desktop computer cases and computer tower cases. Below are the key features and differences between the two types:
1. Desktop computer cases are typically smaller and designed to sit flat on a desk. They are often used for home and office PCs and have limited expansion options. They are also typically less expensive than tower cases.
2. Tower computer cases are larger and designed to stand upright on the floor. They are used for more high-end and advanced systems and offer greater customization and expansion options. They generally offer more space for additional computer components, such as larger power supplies, multiple hard drives, and multiple expansion cards.
3. Tower cases can be further classified into mid-tower and full-tower cases. Mid tower cases are smaller and more affordable, while full-tower cases are larger and offer even more expansion possibilities.
4. Some other types of computer cases include cube cases, SFF (small form factor) cases, and HTPC (home theater PC) cases. Cube cases are smaller versions of tower cases with a cube-shaped design. SFF cases are even smaller, designed to be compact and portable. HTPC cases are designed specifically for media center PCs and often resemble AV equipment.
5. The material used for construction are also different. Some computer cases are made of plastic, while others are made of aluminum or steel. Each material has its own unique advantages and disadvantages.
