You could look at: http://www.raspberrypi.org/
to see if the bare board is still available.
It would be simpler and less hassle to get the full board and add the specialized USB hub or adapter for plug. If you use the Pi locally then a USB keyboard/mouse with monitor should be used or use 'ssh' into Pi via Ethernet.
Mini-A or Mini-B adapters are available to adapt to Micro USB.
Mini or Micro USB
identifies the type of connectors.
Personally, I would not hack a Pi board but use adapters for specialized port connectors.
