From a comment on the article, that could be applied to a future quad-core Mac Mini derivative:
"I would love to seem them cannibalize their lack luster, overpriced iCloud by introducing a “personal cloud” home server product (that would also be the hub for HomeKit, and all that other stuff). Apple getting back to their roots as a high-margin value added hardware company. NAS systems are terrible, especially when trying to integrate them into a macOS and iOS network."
You're thinking the Time Capsule, which is basically an Airport base station with a hard drive that can be used for Time Machine backups. I don't know what other functions it has.
