REad the rules, you might find that if the individual components can be used in different configurations, and you buy several components that work for your configuration, for under 400 each, it's ok. But if the components can only be assembled into one configuration, then you have to keep the price of the whole thing under 400.

From the web page, it looks like it's a one shot deal, and it costs over 400, so it would be illegal. But that's just my interpretation.
