I'm planning on putting a side panel w/ fan on my Dell to get better cooling, but don't know where to start. The Dell side panel is made out of aluminum so I don't want to bother cutting a hole out of that. What do most people use? Just thin plexiglass held up somehow? Do they sell panels with holes already cut out? As far as fans I've read that the 80mm does the trick, is that right? Any ideas, advice, or EDU links (OT & non-OT) would be appreciated.
