custom computers or custom laptops. The hardware in the ready-assembled units would suffice as a norm.
A custom computer is needed if one's work or usage demands a more sophisticated system. A graphic designer friend of mine has been using custom computers all the while. He picks out the parts that he needs and have them assembled into a computer that meets his needs. According to him, a custom computer is more robust, of course more sophisticated in terms of attributes, and a lot cheaper vis-a-vis one you get off the shelf and with less attributes.
As for a custom laptop, he hasn't found a store to do that yet. He's using a Macbook at the moment.
