Want to replace your ISP-provided router with a custom firewall? You’ll likely be considering a device to run OPNsense, and that’s precisely what we have here with the Glovary N100 6L mini PC. While it can run Windows and Linux without much issue, this thing is best suited to running a firewall software such as OPNsense with its six Ethernet ports and passively cooled nature. Usually, you’d be expected to pay around $300, but it’s on sale for Prime Day at just $235, including RAM and storage!
