I'm not sure why you would want to build a starbase that costs exactly the same number of all three resources. But here is some info on that anyways. In general, this is extremely hard to do. Most components use far more minerals than anything else--with the exception of Organic Technology which uses predominantly Organics. Except for organic tech, many components use *some* radioactives but nowhere close to as many as minerals.

Stellar Manipulation components are unique, however, in that they require an equal amount of all three resource types. If, for some reason, you wanted to spend as close as possible the same number of each resource type, your best bet would be to build a starbase with Stellar Manipulation Components on it. You would still spend more minerals because of the vehicle control components on the starbase. But at 50KT across the board for the average SM component, the design will be pretty well balanced.

By the way... if you are asking this question in the context of the TwinGalaxies tournament, let me know, and I'll tell you the cheapest way to build a StarBase (gleaned from the teachings of the beneficent guru Drake, of course...)
