fudpex, what ever happened to the laptop thing? Are you tossing that out the window now?
Also, that alienware is not a good idea. The specs look good, but there are no customization options on dell-built computers. Basically, you're getting a computer that doesn't allow you control over your hardware, and for me, that's a deal breaker.
That case is fine, albeit overpriced for what you get. I still like the NZXT Phantom better due to its extra space, sleek design, and other features that aren't found on any comparable Antec case. However, this is your call, so if you like it, get it.
