Configutator help

I’m going to sell some products having price but no inventory or stock level with zero. I want to disable the “Required products link” being added with Master products. For example

Master Product: Compaq Presario Desktop PC

Required Products:

Asus A8N-SLI Deluxe NVIDIA nForce4 SLI Motherboard $119.99

Biostar K8M800-M78 Socket754 MBB w/Sempron 2800+ CPU-New $114.95

or if this is not possible then hide “Add to cart” button for products having “0” stock level. So the customer will not be able to add that product after clicking on it’s link.

Thank you
