Even with its burgeoning Nexus program, Google is still primarily seen as a software and services company rather than a hardware designer.

Servers are Googles most important computers Google already designs its own server systems — right down to the brightly colored cooling pipes — so taking that a step further to customizing the chips that drive those servers actually seems like a logical move.
