Need help with build for 2D animation

I'm an Animation student and am about to begin classes at the Academy of Art University in September. As the title implies I'm wanting to build a custom PC primarily used for traditional/2D Animation. Im totally clueless as to what to look for when it comes to processors,RAM,CPU,graphics/video card,motherboard,hardrives,etc.I would like something top notch but nothing astronomically priced if at all possible. I'm not 100% sure as to which specific programs we'll be using,however I have head talk of Flash and Toon Boom. Other than that I think we may do a little involving 3D,rotoscoping,editing,encoding,etc. Any help/advice would be greatly appreciated. Will try to find out some more specific info and post later.
