APU6B4: 1x SFP, 3x Gigabit LAN, Quad Core CPU, 16GB SSD, 4GB RAM

APU6 is similar to APU3, but it includes an SFP port (transceiver needs to be purchased separately). 

The router is shipped assembled, pre-configured, optimized, and ready to use (unless you choose otherwise).

APU router is the most open-source network device you can buy. It comes with open-source BIOS, an open-source operating system of your choice, and open hardware schematics. It's not locked down in any way.

Hardware supports OPNsense, pfSense, Open-WRT, *BSD, and a number of other operating systems.

Things to consider:

• APU6 is the same as APU3, but it has an SFP port for optical transceivers (comes without a transceiver)
• APU2 supports two WiFi mPCIe cards. APU3, APU4, and APU6 support one. 
• APU2E4 has intel i210-AT network interfaces (theoretically more performant - I haven't noticed the difference)
• APU2E0 is a stripped-down version of APU2E4. It has 2GB of RAM instead of 4, 2 LAN ports instead of 3, and no internal SATA port. 
• You can connect a 2.5' SATA drive to an internal SATA port to expand storage up to 1TB+. (not on APU2E0)
• APU3 and APU4 are optimized for LTE connectivity, APU2 isn't. You can connect one or two mPCIe LTE modems to APU3 and APU4 to get WAN over 3G/4G.
• Detailed comparison of APU2, APU3, APU4. 
• All LAN ports have real interfaces with separate chips. Those are real router ports, not switch ports.

Advantages over competing hardware products

• Completely silent. 0 dB - passively cooled. No moving parts.
• Small: 16.8 cm X 15.7 cm 
• Very low power consumption - ~6W. 
• Very high throughput - 1 Gbit on pfSense, OpenWRT and IPFire. 
• CPU has built-in encryption support (AES-NI), allowing for high VPN throughput.
• Price.

Hardware included:

• APU6B4 Board (4 core, 1Ghz/1.4Ghz CPU, 4GB ECC DDR3-1333 DRAM, 4 x Gbit ports) 
• 16GB SSD (use router configurator if you would like to have larger size)
• Chassis designed for this board. Only black is available for this board.
• Power adapter (small)
• USB cable

Advantages over the proprietary solutions:

• Low total cost of ownership
• No artificial add-ons are required to make your system fully functional
• No additional charges for extra features - everything is included. unlimited users, unlimited firewall rules. unlimited VPN accounts.
• Low power consumption. It won't show on your electric bill.
• No moving parts. This system is designed to last decades.

Router/Firewall comes assembled, pre-configured and ready to use.
