I already have a lot of HDD space, so I don't need that. I am a bit worried about the size of the case, will all of this fit well in there? Do you think that this cooler would be good enough to cool the 3770k at 4.2 Ghz?

Feel free to comment on anything else if you think I could save money anywhere, or get a big performance change anywhere for not too much money.
