replacement window for my rackmount case

[severndigital]

I recently came across a great deal on server cases, however the rear window is currently AT config.

it is removable,and seems very generic in design.

I was wondering if there is a place to purchase just the rear window for ATX config?

I hunted around but couldn't find anything on my own, so i figured i would ask the experts.

thanks in advance.
