YouTuber ETA Prime got his hands on a new single board X86 computer called the N6000. The board includes a 4 Core Intel Pentium Silver CPU with Intel UHD iGPU graphics, and supports up to 64GB of RAM and M.2 drives. It's fully compatible with both Windows 10 and Linux. ETA Prime was able to playback 4K video, and was able to do some light gaming on the unit.
