MikroTik RouterBOARD RB450. The RB450 is a five port Ethernet router with high throughput. The heart of this device is the new Atheros CPU which makes this tiny device a quick one. Tests show that the RB400 series is faster than any other low cost product by MikroTik, making the RB400 series fit right behind RB800 and RB1100AH. The MikroTik RB450 includes RouterOS Level5 - the operating system, which will turn this powerful system into a highly sophisticated router/firewall or bandwidth manager.

Now the MikroTik RB/450 has a free upgrade to RouterOS Level5 !!
