ventilation fix - cool down machine by 10-15 degrees

acer did a big mistake designing the internals of the 6120 they covered up the ventilation holes by gluing metal and plastic over them. on the middle there a tip that is necessary, on its sides use a razorblade knife and carefully cut until you get to the metalband underneath, loosen that too by razor blade in horizontal flat position. then cut it by holding blade vertical and push forwards and up. on left and right side of the metal cover these metal bands with plastic end up close to two more tips cut there as well. now, get ansmall part of the band up after removing the plastic, and grab it with a plyer and roll the plyer around as if you are opening hermetics/herring. job done you got a cool machine!!!
