Review: Fantástico! Uma das melhores escolhas que fiz. Peguei a versão mais completa, com 24gb de ram e ssd de 1tb. Cara, não tenho do que reclamar. Veloz, trabalha bem com multi tarefas, iniciação muito rápida… ótimo pc. Não tem som, mas isso já é previsto. Se tivesse seria ainda melhor!
Review: Paired with a USB hard drive, these make excellent NVRs for Blue Iris installations. The largest installation is sixteen 1080P IP cameras as well as a card access system, and it handles the task easily, typically running at only 20-25% CPU capacity. The first time I got one of these, I used it out of the box on an isolated VLAN for testing. It configured a fresh installation of Windows 11 Pro and was up and running quickly. I monitored it for a couple days and detected no unexpected network activity and no signs of viruses. Since I am using this for a business, I still make it a point to format the internal drive and install my own version of Windows. For home use, this would make an excellent Plex server. For normal people, it can handle more 1080P streams than you'll ever need. I was able to test it with three 4K transcodes (down to 1080P) and it handled it easily, only hitting 30% CPU.

No trap, everything mentioned in the description is correct.I bought another one last year and it works like a charm. It does not bug, it saves space, does not consume a lot and has a big memory easy to use. Mine is dark grey. Plugs are usbc, except for one in the back and front. There are internet and hdmi too in the back. Very good price for great performance
