I recently saw a friend's case for his guns that he made himself, it was the coolest thing I've seen in a long time. He made it like a wooden suitcase, then put really dark leather on the outside, and sealed it air tight. On the inside, he put black silk, and high powered LED lights that lit up when it opened. The best park was he had CO2 tanks hooked up somewhere inside the casing, and when he flipped this little switch on the side, these 2 pistons would extend and make a hissing sound, allowing it to open slowly. I can't even explain how much work he must have put into it, it's movie quality honestly. He won't reveal any of the internals he used to make it work, but I was curious if anyone here would possibly know what he did to make this magic happen. I personally want to use it as a headphone case to hold my cables, headphones, amp, etc. or a better idea would to put a speaker system in it for parties. Any help to see what he could have done?
