True, I wouldn't class anything Autechre has done as noise-y, other than maybe Gantz Graf.
Snares also isn't at all that noisy other than that album he did with Speedranch.
I love the Autechre myspace page, despite how it looks, I'd say it's still more aesthetically pleasing than a great deal of the stuff I see on there, and that's not because I like the way it looks, it's an indication of how awful most myspace pages are.
For noise, try Venetian Snares - "A Giant Alien Force More Violent & Sick Than Anything You Can Imagine". Served best with a FPS.
