Gigabyte's new UD boards are the bomb and in my opinion you get a better bang for the buck than with with the Asus ... I'd look at their X58 boards too.
That Seagate has a lot of horror stories associated with it .. I'd avoid that one like the plague.

I don't buy ATI cards anymore because of driver problems & frickin bloatware, so I'd swap that one for Nvidia of the same price range.
I'd also recommend a 500-640 GB boot drive and a 1 TB for files - I'd get WD black drives, they've been good to me.
