how do i remove a sound card from my computer?

[snooks]

am having a problem getting into the back of my computer to remove the sound card, there must be a simple way of opening the case to my desktop!

btw, it's a Dell Dimension 5150

Have you unscrewed it? check for hidden screws under sticky pads etc.
Then it should just slide off.

fiodyl - there are 2 screws on the underneath, if i unscrew there should it slide open?
