The reason for the seperate boards is simply that to use stripboard as one big board, I would have to break hundreds of tracks to stop all the cicuits from joining to each other, if you get me. Also, yeah, its very modular, and it would help me find fualts if something failed.
I agree, it does look horrible, and i'm worried some of those wires are going to be a bit on the short side :x . I would do colour coding, but it would mean buying a lot of different cables, and the extra cost that entails. Don't worry, you won't see it when its in its case :lol:
