Just got an HP chromebox to replace a Minix box and its soooooooo much better running LibreElec. Haven't had an issue and I'm updating Milhouse alphas almost every day, runs perfectly.
Just buy a Wetek hub. Everything is already in the Box, no need to buy a case, remote, power plug, hdmi cable, SD card ... And it is much more powerful than a RPi3.
I use a WeTek Hub, it does all I need it to do plus more (4k, audio passthrough etc) and it's not expensive. I used it to replace an ageing Intel build based on Zotac ZBOX.
