I have the connector on all 8 of the cards.  It is just a regular DVI to VGA adapter with resistors in them.  Why?  Well they are there to trick the computer into thinking that a monitor is plugged in.  Otherwise the cards don't show up in windows.  I use Logmein Free to remote into the computers to start / stop the servers.  They are set to turn on on power failure, so I can always restart them by unplugging them from the wall and plugging them back in.
