Final Update: As far as I can tell- the USB-C port isn't functional.  Amazon was kind enough to send me a second unit.  I tested it with a second USB-C hub that I purchased after the first one was ignored by the Beelink PC I have been using.  That one caused a BSOD when I plugged it into the PC (with nothing plugged into it at all)- I did that twice.  I tried that first one again with a power supply.  It didn't cause a BSOD- but was utterly ignored by the PC (Windows 10 device manager showed nothing new, there were no prompts or notifications, and it ignored a USB flash drive which was plugged into that first hub.  The second hub is also ignored by the second Beelink PC.  I conclude that the USB-C port is non-functional.  Perhaps it can be used to power the PC, but that doesn't make it a USB-C port, does it?  I bought a 100W PD supply to power the hub.  I also purchased some USB-C cables and adapters- all for nothing.  I also just discovered that their driver downloads are hosted on mega.nz.  I am leery of that because in the past, that site has been notorius for malware, child porn, and other scourges.  Would new drivers help?  I will never know.  I am a software developer and an EE, and now I'm also a disappointed customer.  So instead of five stars, I amend my review to one (it is going to be a big pain to migrate to another machine-already purchased- to get a working USB-C port that supports connecting a hub with a third HDMI, I have to migrate my Macrium Reflect and my Security suite licenses and reinstall a bunch of stuff and copy data for my browser and eMail clients as well as about 50 other applications).  Kudos to Amazon for taking care of me!  Now to find a mini PC that has all the features they advertise.  Too bad- this is a nifty little machine.First, the package was very small (the packaging box is 13.5x12.5x10.5 cm, approximately).  And the machine itself is much smaller than I imagined (and I have some tiny, 8-core Raspberry-Pi-sized boxes).  But I have to say right off, after setting it up for a couple hours now- that I am very pleasantly surprised.  It comes loaded with Windows 10 Pro OEM.  NO LARDWARE!  Just clean Windows 10 (which I customize heavily for myself)!  In fact, the only indication of Beelink is the boot splash screen.It's generally quiet, too.  But under heavy load the fan can get pretty loud (about as loud is the one in my i7-based laptop).  I'll post more after I have more experience.After 4 days, I was delighted.  At up to 65C, The CPU runs a little hotter than I want (I prefer 50-ish), but the normal CPU temp is in the 40's.  But I might have to hack this later.  I tried to show how fast a 2.1GB file (an ISO file) copies in Windows, but the progress screen appeared faster than I could grab it.  It showed the speed was 1.6 GB/sec.  When I tried again, it was closer to 1 GB/sec.  It's plenty fast for my needs.I've been using it now for over two weeks (4-7 hours every day).  Other than the useless USB-C port, it's sort-of impressive.  The four cores allow running 8 threads simultaneously.  So it always outperforms my needs, it never slows down or throttles.
