So I purchased this after having another Windows HTPC box for my TV.  I wanted something a bit more powerful, as my previous atom-powered box couldn't do 4k @ 60hz.  I got this and it turns out, it can't either.  Very disappointed.  However, since the other box struggled even with 1080p youtube videos (it would turn into a slide show after a few videos had played), I'm going to keep this.  Just so disappointed since the specs all seem to suggest it can handle 4k @ 60hz.Everything else about this box is nice, especially being able to access and change the RAM and HD.  Fairly quiet as well, except when the fan ramps up every once in a while (very rare, usually a Windows Defender check or something).
