"Intel BOXNUC7I3BNHX1 NUC Kit with 16GB Optane memory preinstalled"I purchased this NUC to replace an Intel Celeron-based NUC that recently went kaputz due to a motherboard issue (it's totally dead/bricked).  The little NUC is being used as a small Plex Media Server for use inside the home and the occasional internet stream.  Added an 8GB RAM module (will add another 8 in the future) and the result is a stable little feller tat is able to "direct play" two streams inside the ome network and transcode / stream to one external viewer at the same time all while only using about 50% CPU.  Not too bad.I went ahead and opted for the Intel Optane memory module but have never been able to get it to work. BIOS reports nothing is installed in the M.2 slot while the Windows 10 OS sees the module but states it is Disabled.  Have gone through all the usual Intel-suggested / Intel-Requested troubleshooting but to no avail - their support stinks and is primarily just canned responses from an AI system or from persons in a far away call centre using copy/paste from their approved script ... totally 100% useless.  At this point I've given up on the Optane option - a few bucks down the drain but ... meh ... at least I have an awesome little NUC-based Plex server up and running once again.The package includes a VESA mount to attach the unit to the backside of the telly which saves space.  It was easy to do - recommended.Several have mentioned the blue LED ring on the front is distracting.  This can be controlled from within the BIOS settings along with the power button LED.  They can be made to react to power state or even hard drive activity and can be dimmed quite low.  I've set mine to the lowest dim setting with the ring linked to hard drive activity and the power button LED linked to power state.  With all room lights off it can not be seen.Although I'm connected via ethernet the WiFi is quite strong and stable in my initial tests and the included IR remote receiver works perfectly when pairs with my Harmony remote control set-up.  Bluetooth also has worked flawlessly when using bluetooth headphones to watch a movie.Audio output via HDMI seems to support up to 7.1 channels as reported by Plex and my receiver ... no issues.Overall: highly recommended. Skip on the Intel Optane option.
