Having recently purchased some new neons online for my interior, I noticed that they were exaclty the same as the neons used in PCs. I currently have one in my PC that contains a sound activation module. Unfortunately it only has the 1 output plug for neons.
I was wondering if anyone has done this before? I've managed to locate neons on eBay with a dual output sound activated box, but they cost twice as much to deliver as to buy from the US.

Also there's the slight issues regarding the controls for it, as it's original purpose is for inside PC cases the controls are mounted in a PCI plate. I expect it won't be too much effort to remove them from the plate, but then where to put them?

Suggestions/advice welcome!
