removing the screen assembly on your A75 won't take much effort at all. 7 screws to have completely removed, 3 to temporarily remove while removing the wireless antenna and lcd cable from the systemboard. If you break the little hinge covers after taking off the strip cover you'll have a nice flat top machine.

make sure you've got some good cooling for that thing, it's a beast, also draws a lot of power being a full P4 - be careful.
