Wood glue up help needed

Come on guys, over a hunderd views to my post and no help. Is my question that stupid or the answer so obvious??? Not to me as I am new to all this. Let me know your ideas please.
Thanks,

Honestly, I thought about answering but I was a little hesitant because it’s sort of an unusual design, and I’m not sure exactly how expansion is going to affect it.

My gut instinct is that if the back is not rigidly attached, the whole assembly is going to be shaky. And if the back is rigidly attached, it might tend to separate the sides from the bottom.

You lost me on I already made up the panels by butt gluing multiple pieces together

I don’t see that in the drawing and I second what Charlie wrote.

Wood expands across its width, to a much greater extent than across its length. Arranging the boards as you have will create problems with seasonal movement unless you allow the wood to move. For instance rather than gluing the top to the sides, attach it with figure 8 tabletop fasteners.

Ditto what they said. I’m thinking no glue. Just screws,where the back,bottom,top and sides connect.

The grey lines represent glue lines of butt jointed boards. I probably put more detail in the sketch than needed. Sorry for the confusion

You aren’t butt gluing, you are edge gluing. you are making the board wider and in doing so you will have more expansion from end to end of your box.
Any time you join to edge grain pieces together it’s known as edge gluing.
Butt gluing would be gluing the sawn off ends together.. and isn’t very strong.
