There are some RouterBoards that have built in radios with miniPCIe slots, but these are still “barebone.”
However, having multiple radios of the same frequency on the same board is a bad idea! They will interfere with one another and not work as hoped. You have to even be careful of cards that are down/up converted from the same frequencies.
