As you can see those screws we're really forced in the case it didn't seem to damage the case though it was just very hard to get in. And it was very hard to get them in straight.
What the title says I had a real struggle pushing those screws in I used the right ones the case said and those were a bit easier then the supplied screws from the fans. I used the Corsair HAD RGB 120 for both top fans and rear fan. I had no issue unscrewing the supplied rear fan and moving it into the front but when I tried to put those fans in I really couldnt get it.
