Hi there. I'm building a computer, but haven't done this in a while. Just want to make sure none of these individual parts stand out as either overkill or as not powerful enough (relative to the rest of the system). Also, I have tried to calculate the wattage needed for this system, but am not sure I'm doing it right. In the future I intend to add another Radeon 4870 to run in crossfire, so I need to leave headroom in the wattage for the power supply. Can anyone show me how to calculate this? And one last question, what's a good case that will fit all these components? Thx ahead of time for any help. The specs are listed below.
