Good morning.
As Peter asks, and I also think it's a brilliant idea, I will post here the process of the Metalbox I build for my brother in law's powerwall.
It's an 14S 120P system with the "Bernhard Strunz" style busbar system.
I will start with 14S 80P because thesepacks are already built.
With the packs at the end of the year build the 120PSysem will be around 13kWh of energy, with+/- 10kWh useable.
First thing, what housing to use when you bring your powerwall build to someone else?
They always have concerns like "it will burn" / "my house will explode" .....
So you have to box it into a metal cave. Custom build is to expensive, so use something from the "homedepot" / "Bauhaus" / "Hornbach".
I found a perfect fitting shelf in a "Hornbach" store:

As I need 115cm witdth / 45cm height and 12cm depth it fits perfect.
It has three doors and 2 seperators in the middle where we cut out a big window with only 1cm left around, so the packs can go through.
The build was easy, but I changed some things. So I rotated the backside inside out, so I have a clean one depth inside, not the edges between the 3 backplanes.
An isolater (a old packing from Servers)
As fixing the packs to the backplane I tried different options. This was the best for me:

As you see, upside-down test with 80P no problem, maybe with 120P I will double the amount of clips.
The BMS ( www.energusps.com ) and 4 Fuse/Breakers are also installed.
With 3 doors:
