Well, it matters what are you are intending to do. If you are just going to be doing word processing and excel, than all you need is a barebones system, like a low end core duo processor or even a pentium 4, 1 gig of RAM, either an integrated graphics card or a low end one like a GeForce 6800 or something, and storage.
If you know you are going to be doing lots of work, maybe storing huge amounts of data, or pictures, etc, go with 500gb of storage. Otherwise, go with about 250gb.
And thats about it
