I got this PC from "Quality Recertified" and have set it up as Blue Iris server. The machine itself is well built and all the internal bays are easy to access with no tools. Turns out Blue Iris benefits from 6th gen CPUs, since they support H265 hardware encoding/decoding.The machine itself is quiet and it seems well built. Typical office PC. Yes, it is proprietary motherboard and relatively week power supply, but there are2 extra HDD slots and disks are easy to add / replace. So I wouldn't recommend it for a gaming PC, but for a home server, office machine, it is great.Initially my machine came with a defective SSD. It seemed new, but very cheap and Win10 will randomly crash trying to read its system files. I contacted the seller, they promptly sent a new SSD (different cheap brand) and the new one works well. So, very happy with the support.
