Recommended hardware to replace WRAP board?

Hi all,

I'm looking into the process of replacing my WRAP board with three
ethernet ports at home, partly because of 1.80 now requiring more RAM
than I can ever put on this system.  But I'm frugal.  

Looks like I could get an ALIX board from pc-engines.ch for about $105
+ shipping and just do a swap.  They also have a new AMD powered board
coming out in Feb 2014 hopefully which will even faster for about
$140, but I'll need a new case, power supply, which will drive the
cost up.  

I'm even willing to go Ebay as well... any thoughts?

John
