Hi Caleb~ This paragraph nails the heart of what makes desktop systems—and some laptops—so enduringly useful: modularity. The ability to evolve your rig with expansion options like PCIe slots, additional RAM channels, or extra storage bays empowers users to shape performance to their specific needs without reinventing the wheel. You might even take this one step further by exploring hot-swappable components or external expansion docks for laptops, showing that upgradability isn’t limited to desktops.
