Yup, it is, have to be very careful, the unit is very stupidly designed inside, the speaker is connected to the back casing and 2 VERY THIN wires are connected to the system, if you didn't know this, you pulled the back casing open fast, viola, there goes your speaker.
After that you will risk exposing the LCD also, so need to be very careful no hand/finger prints on it.
But once you're thru with 8 + 4 + 4 screws, you're safe.

wanna DIY?
