Driving a Wedge

In an earlier post, I wrote about the sound card which was hitting the video card fan since it was so close together.  I gave the on-board audio a try but found it lacking.  So what to do?  I decided that some sort of wedge was needed to keep the card apart.  I found a red rubber washer in my toolbox and electrical taped it to the back of the sound card.

Not only does this keep the cards apart but also gives a bit of room for airflow.
