Z-Force Power Pack construction is a heavily armored box case.
Dimensions for the full Monolith are 10" width, roughly 17" height and 14" depth.
The Long Brick enclosure for 2017+ models is the same at roughly half the depth, and of course the storage area on S/DS models with this Power Pack has about the same dimensions minus clearances and dividing bracket allowances.
