Wireless repeater hardware recomendations

  • just looking for a solid hardware platform that will be used on tower tops for my small wisp system (120 users).  have used wrap boards for years but that time is comming….. you know.  Really like PFsense and would like to hear from the knowing world if there is a chance that an ADI pronghorn or Metro board would work in this application woops nope only 64 megs of ram.  Mabey a gateworks... nope again no more ram and also no CF slot.  How about a alix2d2 well its got the ram the CF but only 2 mini pci slots and not that much wattage per slot also!.  Kinda looking slim so the question remains.  Any recomendations?
