It it is anything like the Ferrari 3200 then the build quality is good. The Ferrari is also made of mostly plastic but owners have commented on a solid feel to it with a excellent keyboard. In general Acer's computers are quite nice.
Boy that's sort of a loaded question for me Jokul. I have the 800lci as well, which is the same all aluminum/magnesium body of the newer 8000 line. With that in mind, the best way to put it is like this...it's as good a construction as can be had with an all plastic body. It doesn't feel like a tank the way the 800lci did but it's still very nicely put together.
