@dpsi:
Hey, I came across this system aswell but I passed once I saw that it did not have atleast 2 NICS. I found something similiar with dual intel NICS

Typically you want to use Intel over Realtek as they use less CPU interrupts which equate to better performance for the overall system and not just the network.
I'm currently setting up another jetway, also with dual Intel NIC. It has a better CPU and is part of their longterm support program: http://www.newegg.com/Product/Product.aspx?Item=N82E16856107148
Setup was a breeze, both hardware and software. The wireless card that comes with it doesn't work with FREEBSD though.
