Good point. Are you custom building this, or did you find a COTS
solution?  Have you looked at mini-itx (which I now know of thanks to
Pete)? If so, what was your impression?

Wow. Thanks. I didn't even consider that point. I will definitely make
sure I check this.

This is a problem for us. However, other members of the group, namely,
the UAV guys, seem to think we're okay on this.

Thanks for the reply, Thomas.  I really appreciate the advice.
