In addition to physical security there's hardware longevity as datacenters tend to be both more efficiently cooled and cleaner than the average home, efficient network interconnect rather than consumer-grade hardware on consumer-oriented last-mile infrastructure, redundant power... the list goes on and on. It seems like the grandparent poster really should rent part of a co-located rack instead. I don't think there's much sense in hosting locally in a home environment with Google Fiber for almost any use case regardless of their ToS or the service's quality: for a system serving user requests a home doesn't deliver reliability or redundancy, for a lightly-utilized offline processing system a cloud provider is almost universally cheaper, and for a heavily-utilized offline processing system power and cooling costs become competitive with a datacenter relatively quickly (not to mention the cost of downtime - if you're at high utilization, downtime will cause your job queue to build rapidly and possibly insurmountably when you can't supply burst capacity).
