You can use that in addition to some velcro or something. I doubt you will have many instances where the cp comes unhinged accidentally. If you can find a way to easily get clamps in there and have access to them, then that's probably the way to go. Based on your design, it just looked a little tough. Just trying to throw out suggestions.
What are your options of just screwing down a thin piece of wood in front of the monitor on top of the CP? You could paint it the same color as your cabinet and it would be hardly noticeable. Since you'd very rarely want to get under your CP anyway, it's a fairly simple and elegant solution. I believe there are a few builders who have used a similar solution around here.
