All parts have been ordered. I'm using the same items that were used in each of the posts linked to in my first post. I also met with my designer for the first time today to talk about the project and I should have a rough draft of what the case will look like in a few weeks. Right now we're either going to have the case 3D printed and then have a custom vinyl wrap made for it to make it look nice, or we're going to have an aluminium shell made with a thin, flexible plastic insert that will hold all of the components.
The final product will be about the same thickness all over as the stock 10v is at the back, but 1.5-2" deeper (almost square). This will provide ample room for the internal components that will be added. If our prototype shows that we have lots of room, we'll shrink it as much as possible.
