oooooh... I've done this kind of thing.  You'll spend some time 
figuring out how to power multiple mobos with one PS. For one thing, 
you'll have to scrounge up the correct connectors and deal with any 
of the feedback lines from mobo to ps (like standby/on, remote 
voltage sense, etc.)

Pretty soon, you've spent more in connectors, wire, solder, shrink 
tubing, etc., than just buying more power supplies.. not to mention 
your time, which could be profitably spent doing more useful things 
like drinking beer.

Look at the big totes/toolboxes. Even has a handy carrying case.
