Let me preface this with the fact that I worked in Windows PC\Server\Network support for over 20 years.  We purchased the ASUS Chromebox 3 for my in-laws for Christmas.  They needed a new PC, and I thought a Chromebox would be even far easier for them to use than a new Windows PC.  The first Chromebox 3 I received from Amazon got a white screen with nothing on it but a shutdown button.  I tried unsuccessfully to flash it back to default, to powerwash it, and to reload it from a USB stick, but nothing changed the white screen.  We shipped it back via Amazon and they sent a new one, which arrived and I was able to setup successfully at my house.  I plugged it in at my in-laws apartment, and they tried to use it for a few days, but they could not get used to the interface.  I bought them a Windows PC, and they are happy with it.  I removed the Chromebox from their apartment and moved it back to my house, and now I get DHCP errors when trying to connect via ethernet and wifi.  I called ASUS tech support, and they want me to RMA this Chomebox back to them too.  No thanks, I'm done with this thing.  I don't know if it's the Chrome OS or the hardware, but I'm reluctant to even try another Chromebox.
