How long did it take you to install Windows 7 including all the drivers?
I actually just finished my system build last night, took me 11 minutes to install Windows 7 from the time I leave the "Partition 1 Hard Drive" window to the screen actually booted and ready to use.
The drivers all depend on how good your internet connection is, just downloading the Recommended + Important Updates, it was like 200 MB total. I have the 10Gb/s service so it only took 2 min 40 secs @ 1.25MB/s.
