These mini PCs mostly seem to be produced in small batches so they pop up and go out of stock all the time.
Here's the only one from my order history that is still in stock and it was fine for me, running as a little proxmox server for virtual machines. If I was going to run
Blue Iris I'd probably go for one with a SATA 2.5" slot or at least a second M.2 slot.
This one seems okay with N100 CPU, two network adapters, two M.2 slots, 16 GB RAM and 500 GB SSD preinstalled, for $132.
The thing to keep in mind is these are almost ALL from little Chinese companies and it is a roll of the dice whether it will have issues or if they will honor any sort of warranty. In fact some of them are certainly doing product review manipulation (more on that below). I've bought around 8 cheap mini PCs over the last few years from random amazon and aliexpress sellers and they mostly work just fine. Only two had issues:
1. The most expensive one I got happened to be from one of the better known brands "Minisforum", and it freezes or otherwise goes unresponsive sometimes (which sucks because it is running at a remote location) until power cycled.
2.
This I paid $100 for late last year before tariffs, its heatsink did not make physical contact with the CPU at all so it would overheat and thermal throttle and just run like crap. I was able to fix this by installing a thick thermal pad and then later fix it better by putting a small copper shim in there with extra thermal paste. I left a bad review and the seller immediately found my order and sent me a message through Amazon offering a full refund but then gave me the runaround via email for about a week asking me to change my review to 5 stars or delete my review. I wasn't going to do that, and I pressed them on it, asking if the refund was conditional upon me changing the review, and they wouldn't admit to that (because it is against Amazon's terms of service). Ultimately they backed down and gave me the refund. They absolutely were seeing some success from this review-change-bribing tactic, as I noted several other bad reviews disappeared or changed around that time, and I have no doubt that a lot of other mini PC sellers are doing the same thing.
