Has anyone installed Ubuntu on Dell's alternative to the 27-inch iMac?

It has some obvious advantages including easier disassembly, some upgradeability, and potentially better compatibility with Linux.

Or maybe not. Dell's vague and ambiguous published hardware specs (e.g., it's difficult to see how the base-model's i5-3450s can be accompanied by the 'default' HD 4000 graphics, since Intel says it features HD 2500) make it a bit of a pig in a poke at this point.
