A trip to the Apple store in Salem proved beneficial. The technical 
folks (actually everyone I talked to) were anxious to help. We weren't 
able to get the Mac Mini to drive the Barco monitor but the Mac Pro 
worked perfectly. So my client will purchase a Mac Pro and I have two 
other clients that want the same setup duplicated.

Success!
