Phanteks Mini XL Rattle

I have a spare Phanteks Mini XL, I'm considering putting it back in operation with a skylake build. the only problem is the side panels rattle like hell. Has anyone experienced this.. is there something like very very thin draft excluder or smoke seal that I can line where the side panels slot into the case

I had the same problem with my case.

I just used some electrical tape on the edge of the case and side panel where the side panel slots into. (may have to do all 4 sides of the panel if it's really bad)

cheers, I will give that ago.. once I got budget for other bits
