for uv setup, i think ur pc must have alot of uv stuff like fans, cables etc......
then the effect will more glow......
if not much uv thing then no use if u using uv setup......
i used uv setup b4 this.......but change to led setup by using SMD led.....

coz not much uv stuff.......
one thing that i like about led setup that u can put anywhere u like.....
unlimited place and can hide it

, not like uv lamp that only can put certain place n sometime cant hide.......
one more thing led setup is cheaper.....
also can mix color like blue+green=aqua or red+blue=purple......
