The easiest way i do this is to start off with at least 24in cables if you can get longer, get longer. I then attach them to the Mobo and run the along the bottm of the case towards the front panel. I then run the behind the drives and the over the top of the drive and connect it. This method works best when using RAID cause one cable per drive looks better in the long run. I use two sided tape or velcro to keep the cables against the front panel metal. NOTE this does not work in large cases as you would need 48in cables to reach drive bay one and two. This is a nice easy way to completely hide the cables. Also, try not to run any cables under any other drive *IE running duals hard drives in bays 3 and 4 with a cable in between them which will cause a lot of extra heat. instead run both cables over the top and connect from there. The left over heads can be roled underneath and fitted with pressure to hide underneath the bottom drive. OK, if you are not confused by now then you haven't been paying attention! I will try to get a pic or two up of what I am talking about as soon as I may. It is to confusing to try to explain it.
