Installed 8GB into this thing and am running Mint Mate 20.  I then installed NextCloud v22.  This thing runs loud most of the time.  It has 'bog-all' to do most of the time except stay awake so I have no clue why it runs so hot the whole time.  I mean what it is doing exactly?  NextCloud needs nothing in terms of processing.  I adjusted the BIOS to run in 'efficient balanced power mode' and it has made no difference from high power mode.  Overall, it gets the job done, hence the 3 stars but I'll wager she blows pretty soon owing to heat and general fatigue from doing whatever it thinks needs doing.  Have it connected to a RAID 1 OWC external hard drive setup (USB 3).  All works fine but the NUC's fan runs constantly and is noisey so, would not recommend.  Might replace with a MinMint Pro 2 if that ever become available again but I do not expect ongoing success with this.  It sits behind my TV and can be easily heard(fan).  Annoying.  After some research, I will likely replace it with a Raspberry Pi 4B+.
