     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to computer chassis that house computer components. More particularly, the present invention relates to a flexible computer chassis that is adapted to receive a number of different types of computer components, which have different configurations and sizes (e.g., baseboards of different sizes, peripheral and processor fans having various configurations, and different power supplies). 
     2. Art Background 
     An essential component of any computer system is the computer chassis that houses all the other computer components. As technology advances, computer users desire greater speed and computing power for the ever advancing software applications that demand greater memory, and processing speed. In the past, the new memory requirements and processing power, required by these new applications, could be satisfied by either upgrading the baseboard (also known in the industry as a &#34;motherboard&#34;) with additional memory cards or by swapping processors. 
     However, as software applications demand further processing power and memory (e.g., real time processing, multimedia application, and teleconferencing), many users have found it more practical to completely replace their baseboard with a new baseboard, which is integrated with a new and more powerful processor, and additional memory and Input/Output (I/O) subsystems. As the cost of new baseboards (e.g., pre-configured central processing unit (CPU) with memory and I/O subsystems) has decreased, the feasibility and desirability of simply replacing an old baseboard with a new baseboard have increased. 
     Prior art computer chassis suffer numerous disadvantages. First, prior art chassis are designed and manufactured to house only one baseboard having a predetermined size and one predetermined configuration of computer components associated with that baseboard (e.g., fixed mounting locations for I/O and CPU fans, fixed support mechanism for add-in I/O or memory cards, and fixed locations in the I/O panel for allowing connection of the baseboard with other computer devices). When a computer user wishes to replace an old baseboard with a new baseboard, he is required to purchase a new chassis that can house the new baseboard and associated components. This need to replace the computer chassis greatly increases the cost to the user. This excess cost is multiplied by the number of times a computer user upgrades from one baseboard having a predetermined size to another baseboard having a different size (i.e., a baseboard having larger dimensions). 
     Another disadvantage of prior art computer chassis from a computer manufacturer&#39;s point of view is that a manufacturer must re-machine a new chassis whenever the configuration or size of the components of a computer system changes. For example, when a new baseboard has increased dimensions (e.g. length and width), a computer manufacturer incurs substantial costs to re-tool and to re-machine an existing chassis so that it can adapt and house the new baseboard with its associated computer components. This additional cost to the manufacturer is passed down to the computer users, further increasing the cost of the computer system. 
     It can be seen from the foregoing that it would be desirable to provide a flexible computer chassis that can be adapted to receive computer components of varying sizes and configurations. 
     SUMMARY OF THE INVENTION 
     From the foregoing, it can be seen that it would be desirable to provide a flexible computer chassis that is adapted to receive computer components of varying sizes and configurations. It would also be desirable that this flexible chassis be easily adapted to house these computer components of different sizes so that a computer user can upgrade his computer system without having to buy a new computer chassis. Accordingly, the present invention provides an easy to use, relatively inexpensive flexible computer chassis that is adapted to house computer components of different sizes and configurations. 
     The invented flexible chassis includes four key components. First, the flexible chassis provides a printed circuit board (PCB) mounting plate that is adapted to receive baseboards of different sizes. A baseboard is mounted to the PCB mounting plate. The combination of the baseboard and the mounting plate is then coupled to a side wall of a chassis wrap. When a user wishes to upgrade to a baseboard having a different size and configuration from a current baseboard, only the PCB mounting plate need be modified (i.e., new mounting locations on the PCB mounting plate will adapt the baseboard to the flexible chassis). 
     Second, the flexible chassis provides a rear I/O panel that is adapted to receive different patch panels. Since the I/O connectors of different baseboards vary in location, a user simply couples an appropriate patch panel to the rear I/O panel to adapt a new baseboard to the flexible chassis. In prior art systems, a new rear I/O panel would need to be re-tooled and re-machined so that the rear I/O panel would support the new baseboard. 
     Third, the present invention provides a vertical bulkhead that has a plurality of mounting locations for different fans assemblies (e.g. CPU and I/O memory fans). As a baseboard changes, often the location of the memory, the CPU, and the I/O bus slots are correspondingly changed. These multiple mounting locations in the vertical bulkhead enable a user to positions the fans in their respective positions to maximize the cooling effect on those computer components that generate the most heat. 
     Last, this flexible chassis provides a relocatable printed circuit board (PCB) support rod assembly that may be adjusted and adapted to support different memory and processor cards that are plugged into the baseboard. Since different baseboards often have different bus locations and slots, and these cards that are plugged into the baseboard often require mechanical support, the relocatable support rod assembly provides a flexible way to provide the support to these processor and memory cards.
