I thought I had seen something about binding daemons into machines to make giant daemon engines. I want to use one of these against my kill team, but I can't seem to find the information. I may have dreamed it up. Can someone help me out here?

The Irradial Cogitator, in the Radicals and Heretics section of MoX.

That seems to be just an evil supercomputer that controls other machines. I was hoping for something like the hulking thing in the Salamanders audio drama I heard a few months back. Kinda like a juggernaut of khorne on steroids...

Ah, I see what you mean. You mean something like a Chaos Defiler?

That's what it sounds like to me. You can find the Defiler's stats in RoB pgs. 191-192. I think it also gets a mention in the last adventure of TEP.
