here is how i did. Personally at the beginning i had some trouble to fix the servo but this way, with screws, i can keep of the servo if i want. anyway there are a lot of stuffs inside, and expecially if you want to add the cooling fans, the space inside become smaller and smaller xD
PS: all the inner surface had industrial velcro so i can try different locations of the electronics stuff, batteries , fans etc...
