There are indeed no rules to follow when it comes to noise music and how you "should or should not" organize your pedal chain. It is all about your own taste or what you might be aiming for. Putting the reverb at the end of the pedal chain might indeed allow you to get a wider effect, but eventually also loose some details, depending on the fx level and decay, just to give an idea. I guess "conventional" musicians might put the delay after the reverb, for example, but I do think the other way sounds much better. When it comes to distorsion/OD/fuzz, it's also interesting to notice the way it will influence your sound, depending on the position. As it was stated in the previous posts, this kind of pedal fx at the end of the chain will get everything dirtier. I honestly really like to put a fuzz before a modulation pedal - flanger, chorus, phaser, etc, and even before all of that, a delay pedal with a boost not to loose some details. It's fun, it works, the results tend to change. It also depend on your sound source as well - pure feedback, no imput, contact mic, synth... and so on. Only one advice: let your imagination do the work and ignore every "rule".
