Järjestelmäyksiköt

Järjestelmäyksiköt, often translated as system units or computer cases, are the enclosures that house the main components of a computer. They are essential for protecting the internal hardware and providing a structure for the system. Inside a typical järjestelmäyksikkö, you will find the motherboard, which is the main circuit board connecting all the other components. Also present is the central processing unit (CPU), the "brain" of the computer, and random-access memory (RAM), which stores data the computer is actively using.

Other critical components housed within the järjestelmäyksikkö include storage devices like hard disk drives (HDDs) or solid-state drives (SSDs) for long-term data storage, and the power supply unit (PSU), which converts wall power into the electricity needed by the computer's components. Graphics processing units (GPUs) for handling visual output, and various expansion cards for added functionality, are also commonly found inside.

The physical design of a järjestelmäyksikkö can vary significantly. Common form factors include desktop towers (full-tower, mid-tower, mini-tower), small form factor (SFF) cases, and all-in-one designs where components are integrated with the monitor. Ventilation is a crucial aspect of järjestelmäyksikkö design, with fans and vents strategically placed to ensure proper airflow and prevent overheating of the internal components. The front panel of most järjestelmäyksiköt features power and reset buttons, as well as ports for connecting peripherals like USB devices and audio jacks.
