PCFers have been so helpful in sharing their configurations for Apache 3800 cases. I studied what you all did before I set up mine (photo below).
I was originally planning on 4800s, but went smaller based on one factor: where we play has some semi-skinny staircases, plus I'm a big guy. 3800s give me and the cases a better chance of fitting through without bumping the walls repeatedly.
My initial concern was getting 1000 chips to fit in a case. But I was able to Tetris it and make things work.
Re: the photo, it's eight flat Justin racks (four underneath, four on top), plus two vertical racks. Note that one of the vertical racks is placed under the handle, with no padding there. Why? Because if I were to drop the 3800, it would not fall on its handle, it would fall on its feet/bottom or perhaps any other side, so the shock would already be absorbed by several layers of padding. And if I somehow purposely dropped it handle-down, the handle would hit the ground first/absorb the impact anyway. That rack under the handle is super snug, yet somehow easy to take out. Top foam is whole, bottom foam is whole. Only the middle layers have been cut, as you can see. All the foam is coated with Plastidip (if I were to ever set up a case again, I might find an alternative to Plastidip or something entirely different from the foam solely to avoid using Plastidip. It was noxious stuff, even though I used it outside. I also left the coated foam out overnight so the smell dissipated).
I have 1k chips, with room for buttons, two setups, cut cards, and cash bag. The lid closes easily even with all those things on top of the racks. Snug, but not bursting at the seams, so to speak.
Thanks again to all of you. Just trying to give back/pay forward.
