The new Ultra power supplies allow you to have as many or as little amount of cords plugged into them as needed, a great way to reduce clutter.
Fitting a filter between your external fans (remembering to clean them once in a while as well) helps keep dust to a minimum (there's no way to complete avoid it.)
Canned air or a compressor (with variable power settings so you don't blow your computer to bits) is a good way to give it a good cleaning once in a while (make sure you're outside and if you have allergies put on a face mask.) Make sure you get all your fans, heat sinks, inbetween drives in the bays and in the power supply. (I'm kinda OCD when it comes to it and I take my power supply appart to clean it as well.) If you want to make your computer shine, use electrical contact cleaner and wipe it down.
