yep, I have thought of exactly the same thing.
Actually, a 10 or 12U road rack isn't really all that much if you go with 
some of the newer chinese manufactured brands.
Yeh, obviously far more than a milk crate, but under $200 for sure.
Probably about the same, or less than a pelicon case of the same size.
Of course you would have to get rack shelves as well which can get a little 
costly per each shelf...but at the end of the day you've got a rock solid, 
impact resistent, fairly weather proof box with wheels and handles for 
transport.
Other instrument cases could also work for mounting equipment inside...the 
newer hard plastic flight cases that are square or rectangular shaped could 
work well enough.  And then you've got something you can cary with one hand, 
and that will lock as well.
Anyway, there are lots of possibilities.
