Wood won't ignite until a temp much higher than the card would have already fried at. It's safe to use but it won't allow for airflow.

What works well - go to walmart or target and get the wire dishracks - they're coated with rubber - just make sure not to nick them.

A wire dish rack or other type coated rack is a great idea, I hadn't thought of that. Cool

In reference to wood: Although I'm sure it is unlikely that a hunk of wood would ignite, I always side on the paranoid since I have had small brief fires in computers from components failing.
