I needed a performance upgrade for my aging ASRock J5040, which handled my NAS shares and ran several Docker containers. Since it was always on the verge of being unreliable (but very power efficient), I looked for used components that were both energy-efficient(-ish) and capable of delivering good performance when needed. When I got hands on that server mainboard, I went for it because it also has some decent BMC features and has dual FE network interfaces.

Since I don't have a intel-certified case that would guarantee proper airflow, I use a radial fan with a 3d printed fan shroud. This works totally great and keeps the GPU at decent temperature levels.

Currently the system runs Unraid 7. Both SSDs are running as cache pool devices and the HDDs form the unraid array with 36TB net capacity. I have plans for updating the OS to TrueNAS Scale with additional SSDs for write cache and the operating system.
