A computer tower, also known as a computer case, is a housing that contains numerous elements of a personal or business desktop computer. Towers come in a variety of forms and sizes, and they can be constructed from a variety of materials including steel, plastic, and aluminum. Depending on what the computer is used for and how powerful it is, tower sizes can range from very small with few components to exceptionally large, heavy models that are necessary for more complex purposes.


1. What are the different parts of a computer tower?


Computer towers usually contain several elements, all of which are essential for basic functionality. A personal computer tower typically contains the following elements:


Power supply unit: The power supply unit contains a fan and filters that keep the airflow of the computer clean. This unit also converts AC power to DC power, which is necessary for all internal components to function properly.


Mainboard: Also known as a motherboard or system board, this unit is one of the most important elements of a tower. The mainboard connects all other components together and sends signals from these components into the central processing unit (CPU). A tower's mainboard features several input-output ports as well as slots for memory modules and expansion cards. Memory modules are needed to store data temporarily during processing, while expansion cards enable users to add functionality by connecting ports or other devices to monitor connections, Ethernet card connections, USB ports, etc. Power cord storage compartment: Many towers feature storage compartments for power cords, which allows users to keep the power cord safely tucked away and out of sight. 


CPU: The CPU is sometimes called a microprocessor because it is the central processing unit in the tower. It works by controlling all other elements and processes information at extremely high speeds, similar to how a brain controls the entire human body.


Hard drive: A hard drive contains several metal disks that store data in magnetic form when electricity passes through them in a certain pattern, much like how music is stored on vinyl records. Hard drives can range from very small and portable (laptop hard drives) to large and bulky (desktop hard drives), depending on their intended use.   Optical drive: An optical drive (also known as a CD/DVD/Blu-ray Drive) is an element that reads and writes data on CDs, DVDs, and Blu-ray disks. Optical drives are known to be relatively slow when compared to other elements such as hard drives and memory modules.


2. How many types of computer towers are there?


There are two main types of computer towers: desktop and laptop-style. Desktop computer towers usually contain larger components than laptops do because they require more power in order to function properly. Many people prefer the large size of a desktop tower however because it allows for better ventilation and cooling of all system elements such as the CPU and hard drives, which prevents overheating problems from occurring over time.


3. What is an ATX power supply unit?


ATX power supply units (PSUs) are the most common type of PSU power was designed to fit personal computer towers that follow the ATX standard, which means that they should be compatible with most other tower components provided that they were all designed for this same standard. The letters "AT" in the name refer to Advanced Technology while "X" indicates that it can be used in any computer system configuration whether it has one or many components.


4. How much do PC towers usually weigh?


Typical full-sized desktop tower weights around 20 to 30lbs, but some large and bulky models can weigh up to 50lbs or more depending on their size and construction materials. Laptop-style towers typically weigh less than 15lbs for the same reasons.


5. What is a power cord storage compartment?


A power cord storage compartment is a section of a tower's mainboard where users can store the excess length of the power cord away from view and out of the way. Some towers also allow users to wrap cords around pegs or other similar components in order to keep them organized and easy to access when needed. This component helps prevent accidents from happening, such as tripping on excess cord length while walking around.
