Hello everyone... A week ago I purchased Versa U21 chassis because I love it and I got the offer. All well and good, but I found a hole in the front, down between the two legs, where air can enter between the filter and fan .... Meaning it can easily enter the dust too. Now I ask: is normal to be so or something is missing? If that were so designed what can I put there to fill the holes and stop the dust to get into chassis? Thank you.
