Mac help needed.

Since I'm a big Illustrator/Photoshop user, I've always had two graphic boards in my other Macs enabling me to run two monitors. It's so convenient having one monitor to display the artwork and the other one to hold all the Adobe tools.

Last winter my G4's logic board quit, at least I think that's why it won't boot up. Anyway, I have another G4 and the old one is sitting on the floor in my office with the second board in it. It's a Radeon 9600 PCI . My broken Mac was running on Panther, but I've done some checking and the Radeon is compatible with OS 10.4.11 which I use now. So that's not a problem. I also have the necessary AGP to PCI adapters.

My problem is: How do I remove the Radeon board, and transfer it to the present G4. I found the PCI slot it needs to go in, but there's a metal plate covering it. Do I just pop that plate out with a push? (in or out?) I'm afraid I'll break something, not to mention a possible static problem.

Am I just being a chicken? I need some hand holding here. I don't want to disconnect everything to bring to some shop so they can charge me $50 for doing a quick switch a rue.

I'm going to go nuts pretty soon if I don't get my second monitor connected.

Thanks in advance for any instructions you can give me.
