I prefer to add 270 dollars and get a Mac Mini, that may even run as a server If I want to. (I can even install Chrome on it).
There is maybe a market for Chromebox, but for sure we are not that market. :)
I prefer to subtract 100 $ and get a zotac zbox or acer veriton that may even run as a server if I want to. They also are "fast, compact home or office device[s] [that can be] Set up [...] the way you want with multiple USB ports and versatile display options."
