If I were a younger man, I've always wanted to produce a 'server in a box'. Something small, powerful, capable, came with a plethora of click to deploy apps, in an environment that would be conducive with the average homeowner's computer savvy or lack there of. I've seen a lot of mini-racks made with Lenovo ThinkCenters that really look good, could fit on a shelf in a closet and serve the household with privacy respecting software.
But I'm far from being a younger man, so one of you guys take the lead and make a million $$.
