Great housing with restrictions

So what is there to say: the delivery was accustomed quickly, because there is absolutely nothing to complain about. the housing itself is a nice size, the system inside is very well thought out and the cable management works fine. 4 fan were installed, all working tip top on the fan control. Now to the downsides; VLT only delivery conditions, but at the front Mesch games was rubbed some of the paint. but you can see only if you look closely negligible hence. much worse, the bottom two are dust filter. at the first check they were heavily jammed, and can only be solved with a lot of stress (the upper ones are ok). But the real problem is that the dinger inhuman loud clank when untern a fan is installed! that was so bad that I had to remove the fan again, because it was so real unbearable! I do not know if the part is easily broken, or if this is a general problem with strong fans in the lower section, watch from there! I'll think about it again now if I still can insulate the filter VLT something and whether a larger fan with better decoupling solves the problem vlt.
