The document outlines 7 key differences between custom computer workstations and desktops. Custom workstations are optimized for performance, durability and expandability. They have more power to handle demanding applications like CAD and simulations. Workstation components are higher grade and built to perform all day without issues. They are also more flexible, expandable and tailored for dedicated uses like industry-specific software. While initially more expensive, workstations provide better cost performance in the long run for users with intensive computing needs.
