I bought these to evaluate for storage and control plane nodes for my k3s cluster. It have been running as single node k3s for about 4 weeks without issues moving the workload of an older intel nuc. With dual sata ports I was able to mirror the disk and use this as primary contact point for minio (s3) for grafana and loki as well as running a standalone Nextcloud and homeassistant. This allowed me to only spin up a storage server for backup nightly and leave zimaboard handle all the 24/7 workload saving ~ 20 watts. It has less ram but handles the static workloads great and will probably buy 2 more for the 24/7 workload in k3s. Wish they came with more ram.
The build quality was better than expected and heatsink keeps it cool on medium to high load for days in a basement. What I am missing is a diskmount that connect to the board so they can be placed or stacked as one unit.
Overall good experience but like to see a 16/32 gb ram unit with same power consumption spec and a console port.
