I don't think that there is one. There is none listed on Coolermaster's parts shop.
Time to do some modding of your own i think. How is the mesh fitted to your current sidepanel? Is it by little pushpins? If so it's easy enough to remove the mesh, cut a clear panel and fit it to the current side panel.
do you remember where you go it?
