I feel that the "full" spectrum of potential PC form-factors has not been explored yet, and that many people, especially the millions or billions of people who do NOT have a good place to set up a traditional "Desktop PC", would benefit from more "transport-able" Desktop PC designs.
Here are a few concepts for practical "Desktop" PC/Voice Assistant Kiosks that would work well in Kitchens, Dining Rooms, Dorms, Barracks and other less-traditional locations. There are also Construction and Gaming variants.
Note: Most of the designs would benefit from Google Home integration, as they would not only be PC's, but kiosks as well. They could run Chrome as well, or even a switchable combination of Windows and Android.
