I finally grabbed one of those little fanless “firewall appliances” that keep popping up in homelab circles, and I wanted to see if the hype is real or if it’s just an AliExpress hunk of junk. This one is the Topton X2E with Intel’s newer N150, plus the big selling point: four Intel i226-V 2.5GbE ports in a solid, passive-cooled black case. I went over the IO, cracked it open to look at the internals (NVMe, SATA via adapter, and some interesting expansion options), then threw in my own RAM/SSD and ran benchmarks to see how the N150 stacks up. Performance-wise, the N150 is only a small step up from an N100 in Geekbench, and in sustained loads (like Cinebench) it actually fell behind an actively cooled N100 box due to power limits. Power draw also wasn’t amazing for an “efficient” chip—around 10.5W idle in Windows, then closer to 8–9W idle after moving to Proxmox 9, tuning powertop/autoscaling, and unplugging display. The real win is flexibility: I ran Proxmox, tested Jellyfin Quick Sync transcoding, spun up Home Assistant and a Minecraft server, then installed OPNsense both bare metal and virtualized with NIC passthrough. Routing hit basically wire speed, and while virtualizing your router adds complexity, the snapshots and service isolation can be worth it if you’re not using your router host as a constant science experiment.
