We strongly suggest that you buy PC components because it gives you the ability to choose the kind of PC you want to design. However, when you are not about designing your own PC device, then the next best thing would be getting a prebuilt PC machine. It should work just fine. But you don’t get to choose the kind of components that go into building your new PC. Perhaps, you may take the help of a friend who is into designing PCs and take their suggestion. Besides, it is cheaper to design your own PC unit.
