I've been using that MSI board on the test-bench for a while. It's a very solid board, with the only weak spot that I've identified so far being a slow POST time (takes about 20 seconds from power on, until the loading XP screen comes on). I have support requests in with MSI to try to improve the issue.
Also, I built a custom case for it, so I don't know if there are any fitment issues (you would definitely need to get creative if you wanted to use the PCI Express x16 slot, might work with a flexible riser).
As for the VGA/s-video question, I don't have the s-video bracket, but you could submit your question to MSI at: http://www.msicomputer.com/msiapps/ts_form.aspx The motherboard you're looking at is listed under Industrial PC, and select Pre-Sale Questions as the "Symptom".
Let me know if you have any other questions about the board.
