Really nice build, congrats!
I have some questions...
When you tilt the entire case back, the plexi foot with the cold cathodes doesn't break? because it looks like it can hold the case in the vertical, but not while tilting, looks like its going to bend or break, do you take it off?
The hoses on the back should be simetrical, but thats just my little simetry devil inside my head...
I kind of didn't like the wiring of the leds, I would suggest you using smd leds, whici are way smaller and you could pass some near transparent wires... or thin film... but thats a lot harder to do and i don't know if there are smd uv leds... Great Ideas you had tough.

Congratulations, very nice build
