Your build looks fine. But i don't understand why you need a DVD-Burner + a DVD/CD Drive.
Just something like this will suffice:

And a minor detail. If you don't use IDE, than don't get a IDE dvd/cd player. I think it's a waste of space inside your computer to get a IDE cabel hanging around just for ONE dvd/cd-player/burner. Go with Sata as they are small and easier to work away to improve airflow.
And i agree, there is nothing wrong with vista. I don't understand where the Vista hate is coming from. I was sceptical about it at first to. But after using it, I wouldn't want to go back to XP anymore after using Vista for almost half a year. Only downsize about Vista would be the amount of space it takes and the boot time not being as fast as i expected. But Windows 7 should be a improvement on the latter.
Edit: on second thought. The PSU could be better. I don't know that brand, but that wasn't the biggest reason to change it. It's the >72% efficiency. Go with a other brand with higher efficiency. Or spend 10euro extra and get:

Don't cheap out on the PSU. A faulty PSU can drag along your hardware as well when it dies.
