Yeah I spent 4hours trying cable management with my Antec 900 recently, still didn't come out looking pretty but hay I was able to put most of the cables off to the side to not obstruct airflow, but the downside is it looks like a 5 year old did it. Oh and I used half a pack of zip ties to get the job done too, so it really looks like crap when you pop off the back side of the case (if you can manage to pop it off and back on, that alone be a miracle, I don't know how I did it).
So yeah I have to side with you eppinizer, I wonder how people can make those things so well organized.
