i have this case, and the entire front bezel will come off via soem screws in the inside of the case, the acrylic is held on with plastic pressure clips just like old video card heatsinks,. im sure u can figure it out form here.
the battery life is about 2 and a half hours if you are doing decently heavy load liek watching movies and such. if you are just running applications it is about 2.45 hours.
