Today I wanted to clean the fan on my D54250WYKH for the first time. I couldn't. The little piece of plastic in front of the 3,5mm audio jack and IR was impossible to remove and after an hour I gave up because I didn't want to risk damaging anything. All ports except the audio jack only have punched holes for them in the chassis, in my opinion extremely good design decisions. But the audio jack and IR just had to have a little piece of plastic in front of them because... it is supposed to look good? And not only this, the piece of plastic of course has to be attached to the INNER frame, on the sides AND the top. Did the engineer/engineers behind this design come to work drunk regularly? I really want to know the rationale behind this design.
Have a nice day!

Actually, personally I encountered with this situation one time disassembling a NUC.
