Custom PCs are personal computers that are built to meet specific needs and preferences of the user. Unlike pre-built systems, which come with fixed specifications, custom PCs allow individuals to choose components such as the CPU, GPU, RAM, and storage options. This flexibility enables users to optimize performance for tasks like gaming, video editing, or general productivity. Building a custom PC can be a rewarding experience, as it allows users to learn about computer hardware and tailor their system to their unique requirements. Additionally, custom PCs often provide better value for money, as users can select high-quality parts without paying for unnecessary features found in mass-produced models.
