If you see an Octane with DVI connectors for less than $200 buy it without a second thought. All vPro, though, basically look the same from the back. You need to either look at hinv, or physically get the part number off the board. The DVI ports are an option called a dual-channel display adapter (DCD) that plugs into any of the vPro boards, but is worth a couple of bucks on its own.
