I think the M2 Mac Mini is going to put some price pressure on these mini PCs. I have an M1 Mac Mini but also have computers with Windows, Linux, and Chrome OS. Mac OS is not my favorite, but the Mini itself has been great. It's fast and generates no perceptible heat or noise, and it was often available for $549 to $599 in my area. The Beelink has a clear advantage with ports and more memory, but I'm not sure how quiet it will be with a 45 watt TDP processor in a very small enclosure.
The Beelink GTR5 has dropped below US$600 with 32 GB of RAM and 500 GB of M.2 2280 storage. Also equipped with an AMD Ryzen 9 5900HX APU, the Beelink GTR5 is a particularly potent mini-PC, particularly with a 25% discount.
