You have to admit though that the WS-12-250-AC and WS-12-250-DC is a work of art with us (mostly Dave and Robert) getting that much switch in such a small package!
They definitely were very skilled at using the PC board design software to get things that tight!
I noticed you added holes in the top. But I can't tell, do the production cases have a few vent holes on the left side toward the front (under the 9 pin d-shell) to provide some cooling for the 24V regulator circuit? I know you don't want to "short-circuit" the cooling path over the processor coming in from the right side. But just 1 or 2 little holes on that left corner might be useful?
