I've looked at Alienware a number of times but have no actual experience of their systems but I have read a couple of things in computer mags.

1 Tend to be overpriced.

2 Supposed to be noisy

As I said this is just what I read in a magazine that did some tests on various systems!

Maybe someone else will offer some other opinions / experiences!

Injustice will be avenged.
