I received this unit extremely fast (less than a week) from China to California. The device was very easy to setup barebones, I used 3200Mhz memory that is downclocked to 2933Mhz. The down-clock is a limitation of the Intel CPU and is expected. I ran memtest86 for a few hours and there were no errors reported. The device does get hot, but that was only after running it for 2 hours straight at full CPU load across all cores. The device has been running PF sense for the last 12 hours and is luke-warm, which is reassuring.

First- HUNSN was very communicative in their support, contacting me to validate that I was ordering the correct part (The Bare Bones version) and letting me know the list of compatible RAM .

There are no M.2 slots on this particular unit (RS03K).

Very little information included or online about setup or configuration of device but otherwise was pretty easy setup but I did need to plug in a monitor and keyboard for initial config. Has been rock solid ever since. Came with pfsense preinstalled and after a quick run through of setup had replaced my old wifi router without a hitch.

Although this device can be used for a variety of use cases, I went with a standard bare metal OPNSense install.

Love this product 4 usb just wish had more compatable video... but command line is fine for direct interface while remote gui still works.

I was able to install OPNSense OS on here for firewall with ease.

Fantastic device for a firewall appliance.

The product have a really good quality also the team give a great technical support, theyre very kind and willing to help.

Bought it barebones to select my own RAM and SSD.
