I assume Enzo's point is that IBM hasn't offered a physical model mainframe in 
less than a single frame form factor for many, many years. Until now. Prior to 
the IBM z16 AGZ (and LinuxONE Rockhopper 4 AGL) the physically smallest 
mainframe required a whole rack footprint, a rack that IBM supplied. Now it 
doesn't; the physical dimensions are much smaller.

There was some significant progress in recent years to pave the way for these 
rack mount models. One big change was between the IBM z13s/LinuxONE Rockhopper 
I and the IBM z14 ZR1/LinuxONE Rockhopper II. In that model cycle IBM reduced 
the frame size significantly, converging on the industry standard 19 inch rack 
size. And those models (and the IBM z15/LinuxONE III LT2) also have some 
optional internal mounting space for a few use cases. As a notable example, you 
can equip those models with internal ECKD storage (IBM DS8910F).

But I agree with Enzo that these new rack mount models available in most 
countries are attractive. They open up some interesting new deployment options.
