Not used one
But it's a way of getting a more diffused light
Led strips unless you can hide them
You tend to see the leds
Just done a 011d xl build
And that's the issue with trying to put led strip along
The bottom of the glass panel
The black part of the glass is too thin/not high enough
So you see the individual leds
The downside of a light box is it takes up more space
So depending which one it might even take up all the space
Where you would have 3 fans
Other selling point is usually comes with a controller
So don't have to rely on some of the rubbish motherboard manufacturers
Lighting software and should get some nice preprogrammed effects
Though should be able to use the software too
If you want
