When you say UV, is that a specific kind of color light? (ie. UV red as opposed to just a red LED). I was thinking as you said, buy a 120mm LED fan in RED and mount it on the intake on the front of the wind tunnel. Then throw in a 120mm LED fan in BLUE and mount it on the exhaust on the rear of the wind tunnel. That would actually look pretty sick. Then maybe I can throw in a blue below my optical drives since I have 5 bays and I'm only using one. As you suggested, the LED would be hidden. Since my power supply is green, I would have some multicolor craziness. Then again, one color might look much better than three, but two looks better than one. It must be the damned power supply LED.
I haven't actually received the case yet from newegg, but I should be getting it on thursday. Throw my a PM, email, or IM me on AIM sometime around them, and I'll fill you in on it. (email: CMobarek@calzinger.net

Basically the tunnel sections off parts of the mobo. It separates the case into 3 cooling sections. Since the motherboard is flipped upside down (mounted on the left), the CPU & memory are cooled in the windtunnel and separately from the rest of the computer because they are the hotest components. That way, the CPU & memory don't heat up the other components. There is a front intake and a rear exhaust exclusive for the wind tunnel. There is an 80mm intake in the front above the wind tunnel 120mm front intake which cools the rest of the motherboard components. Then the power supply which sits above the the HDD cools them down. Overall, looks to be a very efficient cooling system. You do have to be careful though. Some CPU heatsinks won't fit in the wind tunnel and if you're doing water cooling, well, there must be a better case.
