I bought one with an AMD 4800U in early 2022 to be used as a cheap, dedicated Linux device for work (mostly Remote Desktop plus some local docker development environments) and it’s been rock solid for me.
Your mileage may vary, but I’ve been happy enough with mine for the price that I had already decided I would be choosing Beelink for my next mini PC over a NUC.
That said, I have seen some mixed reports of some issues around thermal throttling and eGPU support for some of the newer gaming focused ones, but I think if you have realistic expectations given the form factor (and especially if you’re not going for gaming) then they are fairly reliable and sturdy little devices.
* Also note, I bought mine barebones and added my own ram and SSD. I can’t speak to the quality of what they ship with, but I also haven’t heard any complaints from others with that regard.
I've deployed about two dozen of them for small business clients who needed the form factor.
Everyone has loved them. I wound up getting one to manage my print farm, and no complaints there, either. Knock on wood, but they Just Work, so far. Noise and heat have not been an issue, even with the oldest units.
the one I have for my daughter is okay. gets the job done but wont use for gaming etc. I do however want to get the Beelink GTR7 [1]. that seems amply powered and decent build quality/noise level.
it seems that from the point of view of the cooling and noise they are significantly improved over earlier Beelink models, so any of the two variants seems like a good choice.
An alternative is Minisforum UM790, which is configured for a lower CPU power and which has slightly less peripheral interfaces.
