"... so, I thought, why not?"

I was concerned that these lighted fans would be too much at night; but, they're more sedate than I'd expected.
 
Each half of the server has three of these. The bottom ones draw air into the case, and the back one pushes air out. With three fans already pushing out the front, the back one might not even be needed; but, I'm over-engineering this as best I can. Silicone gaskets where installed between these fans and the case to eliminate vibration.
 
Thermaltake Blue Orb fans contribute their own glow, and the Adaptec RAID cards are actually quite striking to behold. When the drives aren't active, it falls into what my friends called "Knight Rider Mode", though I actually found myself thinking of Cylons.
 
Does that prove my geekdom???
