I know.. I have it ..
how about making your own guides so you don't have to blame em on someone else
I have a hard time imagining the average joe with their dell asking you to clean up the cable mess.. and if they even know that airflow is something to thing about, they're probably taking care of that themselves.. but ya know.. even if they do ask you to do that, just do what I do! Shove the cables behind stuff so you can't see em! An air can is a nice thing to have.. although I don't have one.. :/
