Go out and find a used Haliburton aluminum case, or something similiar, then build your pedal board to fit it.
The best pedal boards are sloped, with the storage area under the pedals for power supplies and for tucking in the wires, usually with slots running the length of the board for this.
The basic idea of a pedal board is if your are gigging, it is a major pain to always be plugging all your pedals together, in the 'right' order. With a board, you plug in the power, your output cable(s) to your amp(s) or PA and plug your guitar into the input, turn on the power and play.
If you're not gigging don't even worry about getting one.
