Dell Computer's primary consumer business takes orders from customers for specific configurations of desktop and laptop computers. Customers must select from a certain model line of computer and choose from available parts, but within those constraints may customize the computer as they desire. Once the order is received, Dell assembles the computer as ordered and delivers it to the customer. Assemble$-$to$-$order
