First PC build

My built is leaning towards gaming.
List of games I would be playing:
StarCraft series
Diablo series
Command & Conquer series
Guild Wars 2
Civilization
RollerCoaster Tycoon
I want to be able to run the games on their highest setting.
Other uses: watching blu-ray movies, surfing the net.

My questions.
1. Would the case with all this include have ample space for a cooling system?
2. Is the power supply sufficient enough or is it better to get more wattage for future add-ons?

Any general comment about components or concern about a certain component please share. I had more questions but they currently escape my mind.
