I'm not sure about DSA's opinion, and here is the information about
the board. It is an almost standard ITX one, and we've put it in an
ITX chassis retired from a ~2006 Lenovo PC, using its power supply.
The board has some pins for connecting power bottons (Power and
Reset), though we are not using it because it looks not fit to the
connector of the chassis. There is a dedicate button on the board to
power on/off the machine as well. We used the on board button and no
hard reset needed/conducted since successful installation of hardware.
The mentioned ITX machine (6100 model) available for purchase is just
a complete PC box.
Thanks,
