Gold shovel for me 
:
Its pretty late for such thing, and pictures are not avalaible anymore. But
First let's compare size versus Node 202, mini ITX case from Fractal Design. This case is pretty small while in horizontal stand (10.2l), however in vertical stand (due to large base), its dimensions become 125 x 385 x 332mm (15.9l)
The volume of case its not changing... There is a base, but base its creating [if You wrote about this] space around case to breathe. If in horizontal postion, u need also keep some space above N202, because u will boil internals. Same with Cerberus, u cannot put boxex around and expect good cooling. Yes, Cerberus has some front "intake", and back "exhaust", but same story. If those speces would be covered - temps go high. So volume of Cerb should be increase also .
Just saying.
This AR900 its aTHING, and those 4nvme, damm and just yasterday bought some stuff for new project.....
BTW since You have this board, does it support bifurcation on pcie x16???
