I'd forgotten about Falcon Northwest. I have a buddy who bought one of their desktops a few months back. To hear him tell it, it's the greatest thing ever conceived by man. No idea about their laptops but if they're of a similar quality then you're going to end up with a good product.
To be honest, if you go with any of these high-end companies you're going to end up with a good machine.
They aren't clevo based laptops, they are more custom like alienware but higher quality.
