I wasn't really scrutinising the internals... I was rushing since i have a kid to take care and houshold work to do haha. The first cyan case i got from freetrade21 has some speaker problems. So i think his cases are not 100% good. But i am lucky the white one is good. Weird thing is the blue one came from Hong Kong and the white one came from Sweden! If it is your first time changeing, please please use a good screwdriver and take care not to strip the screws. watch the videos and detach/attach the usb cover at the correct angle, so as not to bend it these are the more difficult parts when i first did it.
