All my cables are individually marked, color-coded, rolled, and secured with velcro. It takes a while to get it done the first time, but after that, it is MORE than worth the effort. Once they are all individually rolled up, I sort them into groups as to what they are used for, then strap those groups together. You can go to Lowe's or Home Depot and get these "tool cases" over where they keep the tool boxes. They are like $30 and they look like a fat silver brief case. I find those perfect for transporting cables.
