Yeah, it's a nice small case, but by the time you plug in expansion units for I/O, external drives, etc. you loose a lot of the small factor and you have cable spaghetti across your desk and power strip minefields underneath. For a rackmount machine you often have to plug together different units, but at least it goes in a case to keep it all neat.
It all depends on the price points that these units and the associated thunderbolt stuff reach.
The cable mess is not a big deal, most of those devices can be daisy chained, and there will be an industry of accessories for cable management to keep the Apple design junkies satisfied. Now, if the "cylinder" is priced competitively, the prospect of being able to upgrade the computing of a machine used for video stuff, for example, by simply swapping said cylinders while keeping the rest of the stuff already invested and which moves at a slower pace of development (data arrays, mid bandwidth specialized PCI-E cards, etc) intact could be attractive for the sort of audience Apple may be targeting: professionals or organizations who don't really want to know much about computers, but who need to do stuff with them that requires certain degree of compute power.
The degrees of integration has turned the computing devices into commodities. And apple thus far has made bank by seeing that trend. I personally don't quite care for this device/design personally, as far as shapes of objects go I prefer boxes over cylinders.
