I have now purchased 3 of these small Beelink PCs and one from a different vendor with the same specs, but likely manufactured in the same Chinese factory. Two are used as camera monitors at our church and two as a PC for remotely-managed radio controllers.
They are partially loaded with WIndows 11, which requires 1/2hr or so to complete the upload and setup... possibly not different than other Windows 11 systems. There are 4 USB ports, 2 HDMI ports, a RJ-45 port and a 12vdc power port. Wireless and Bluetooth work well. I have not specifically tested the full functionality of the various ports, other than to say that they work very well for my light-to-medium duty use. The OS is much faster than the systems they replaced in all cases.
Handy for my use, the box contained a bracket and screws that can be put on the PC case. The bracket holes match holes on the back of small monitors intended for a wall mount. My church monitors were mounted on a wall mount and the screw holes were filled, so I used a couple of zip ties to mount the PC to the existing wall mount. Inside the box were 2 HDMI cables, one long and one short. The short one worked fine and reduced the cable clutter behind the monitor.
The two that are working as radio controllers are remote and difficult to get to, so reliability is important. Both are set to logon upon boot and run the specific programs that are needed to control the radios. The system bios has a setting that will power on the system when power is applied to the power supply. Thus, when the power goes down and is reapplied, the system will boot and system will run. This should prevent us from having to drive 90 round trip miles to the site when there is a power failure. An added plus for powering this system is that it runs on 12vdc. Our radios also operate on 12vdc, so this should allow us to run these PCs remotely and on solar power without having to introduce 110v AC. It's early in the life of these, but thus far, both are running without a failure.
I only have one gripe with these, and honestly it was tested with a same-spec system from another vendor (however by the looks of the system, it was manufactured in the same factory and has a different sticker on the front). I wanted to drive 2 1080p monitors from 1 of these PCs. The specs say that it will drive 2 monitors at 4k and I expected it to drive 2 1080p displays with ease. Our camera system uses a web browser to display the camera feeds. When I set it up with 8 camera feeds on each monitor, the system simply choked after a few minutes with very slow display speed and slow response to mouse and keyboard inputs. These PCs use shared memory so there is no dedicated monitor card with high memory. I suspect a nice monitor card would likely cost more than the price of the device. This is the reason I now have 2 instead of 1 of these.
