Actually, it looks like your cables can easily be hidden, maybe you made an effort, but it doesnt seem like it.
1. Those IDE cables, it looks liek they were just tossedin there, fold it a bit an dhide it into other empty drive bays, route it around the back of the drive bay.
2. Wires at bottom of case, those OBVIOUSLY show no effort. . Bundle them up and tape/zip tie it to the other end of the 3.5" drive bay. See those holes? Use a zip tie and make a loop, then put your bundle in there
3. That small bundle in the middle of the window with a rubber band securing it. Why not tuck that into an empty drive bay? That goes for all those other VERY VERY long cables that can obvioulsy be hidden.
4. Lead thats infront of your Volcanoe 12, not a good idea to put it there, molex might get caught in fan, why not tuck it ONTOP of the heatsink, not dangling it infront
well thats all I can help you on from those pics, good luck! and if you do take any of my suggstions, remembre to put some pics
