I have a new Update !
Was very busy, and I have taken my time to pass the time the 140mm intake fan at the back of the case.
Here I have tried this as the dust filter fits.
Times all cut roughly with the dremel.
Use a file and dremel further embellished.
The full file all filed to end, and painted with black color pencil the cut edge.
Here you can see the dust filter with built-in fan, I still need black screws and washers !
Thus, the fans in the case then looks like the screws are slightly too long, be exchanged !
