Thanks... I've looked at Flex ATX, but was hoping to find something smaller for embedded use. I know that laptop stuff is generally proprietary (and expensive, and difficult to get parts for, etc.), and so that probably is not the best way to go in order to make a very small system... So instead I am now looking at some tiny single-board systems from advantech.com (and the tiny cases and power supplies that go with them). Or perhaps some other manufacturer with a "brick" system...
