I am looking for a shopping cart where customers can order a built to order computer system. The system would have a base price where the customer can select a different processor, video card, sound card, etc. Basically everything in the system is customizable. I need the price to be real time when the customer selects a new item. Also the other items would be available product under another section. That way if I want to change a price for an individual product, it would automatically be reflected on the built to order systems. Is it possible to use your cart for this?
 
Thanks in advance.
