Looking at that list of colors the ones that may be the most similar are:
RAL6037 - Pure Green (is a little too dark)
RAL6038 - Luminous Green (the green is a little bit too intense, I think green CPS2 boards are slightly more pale)
Between the two I'd probably say Luminous Green is the one to go with
This was pretty much exactly what I thought. But Luminous looks closer than Pure I think.
The green cases are actually quite a bright vibrant green, I have a nearly NOS one here at the moment I desuicided and it's not quite the Luminous green but it's not far off.
