A tower case is a type of computer chassis designed to house the components of a desktop computer. It typically stands upright and provides ample space for hardware such as the motherboard, power supply, and storage drives. Tower cases come in various sizes, including full-tower, mid-tower, and mini-tower, allowing users to choose based on their needs and available space. These cases often feature multiple expansion slots for adding graphics cards, sound cards, and other peripherals. Additionally, they usually include cooling options, such as fans or liquid cooling systems, to help maintain optimal temperatures for the components inside.
