Anyone have the Thermaltake F51 Suppressor with glass window?

[King Mustard]

I originally had the plastic side window but I bought Thermaltake's tempered glass 'Upgrade Kit'.

However, upon fitting in, it sticks out (is not flush).

I contacted Thermaltake and they are telling me it's normal but I think it looks a bit stupid.

Just thought I'd check with current owners - does it look like this on yours?
