So here's the tubing I'll be using, placed on top of my case. As you can see, it doesn't show its UV blue with the fan's blue LED much, if at all.
Threw the UV LED up via the eSATA port (removed cable due to not functioning) though...
And zing! Well, okay, not quite as impressive still as I'd hoped.
Threw towel on the edge to see if it showed better in the darker area. Kind of, I guess?
