I normally don't post things from makezine/instructables because with all due respect to the makers out there, many of the projects are impractical and end up looking worse and costing more than the store-bought alternative.
But this idea was so simple that it's brilliant!
http://www.machinistblog.com/pamper-your-tools/Basically with a t-shirt, a drawer/box, some expansion foam and whatever stuff you want to store you can instantly make those neat foam inserts that hold objects inside a case.
They show tools, but I was thinking it would work great for this hobby as well, particularly for consoles. Find a nice big box and lay out a console, it's controllers, and it's accessories up-side down in the box and make a custom console shelf. The same goes for the carts, use some spacers to stack them up pretty even and make a cart case.
You could probably get away with using velour or velvet as well, making it look classier.
Somebody would have to see if the expansion foam bleeds through the t-shirt though. While it isn't the end of the world if your pliers get stained a bit, it might be if it gets on your 2600.
