I use milk crates to transport them. I like how the crates are stackable in the back of my Honda Element. I've used the milk crates at gigs in sevearl different ways, such as stacking two of them to create a mixer stand. At one gig the height of the stage was equal to two milk crates, so we used them as monitor stands to free up room on the stage. I also like to store the cables in the milk crates at home, which fit perfectly in an IKEA Kellax shelving unit in the rehearsal space:
