Review: Works fine in D213 2U Istar, has what we need for our NVR build. - Use this board in an NVR build that we do using a D213 Istar chassis. Works fine, no issues. Like the Dual network ports, saves having to add a card. Good value for price point. Well laid out, and fits well within chassis.
Review: perfect for Proxmox build - I bought this to replace my aging Proxmox system that was built on hardware from 2014. The new system has only been online for about a month so far, but this board has served me well and met all my expectations.
