I used the same monitor type. But since monitors are flat these days I ended up just making a flat bezel from black poster board. I cut the opening using an x-acto knife and a straight edge. But I also needed some wood trim on the sides just to hold it down flat (as the poster board wasn't so thick so it wanted to buckle a little).
I had looked at those threads on making your own, which looked great, but which also had a curve to match CRT's. For an LCD you won't want it to curve where it meets the monitor.
