I purchased several container racks (IKEA), with six containers in each. The unit can be put together easily with the instructions that are provided. You can stack the racks, or have them hanging on the wall. Spend an afternoon or two sorting all your LEGO by color, and have an individual container for each color. Some main colors (red, white, grey, etc) take up two containers. Have a container for windows, and one for tires. You can sort your LEGO however you want. When you go to create things out of LEGO, its real easy to find a certain colored piece, as the area that it can be found in is cut down drastically.
