I am running pfSense on it with zero problems. I added RAM and an NVMe drive. It was easy to setup and install pfSense... I assume the same is true for other OSs. It doesn't seem to affect anything, but it does get hot. Like I said... no issues with the tmeperature... it's just hot.

Great firewall running openWRT, beware of NO WIFI CARD and be careful which card you purchase as it may not be supported by opnsense.

The HUNSN RS41: Just as good as my full-sized PC.It came with pfSense installed on a 2.5inch SSD. To make more air-space in the box, a M.2 NVME replaced it.Copying from the 2.5" to the M.2 could be done using dd on a bootable flash drive running Knoppix linux.But I decided on a fresh install.On the RS41 board, I changed the AUTO_PWRON jumper to disable AUTO POWER ON.Not knowing any details about the JP_ME jumper, it was left as is.The board has 2 slots for memory, so the second one got filled - it now has 8GB.Decided not to put wifi internally, but using a USB dongle, which can be pulled or inserted without opening the box.

I purchased this to run OpnSense on a personal (small) Network and it works perfectly out of the box. I've upgraded OpnSense several times and have had no issues.

It only lasted 5 months then it started acting up so I rebooted it. It came back up to all kinds of errors and no boot drive.
