Looks good on the inside, but...
Thermaltake Tsunami is my recommendation on case
I would recommend an Enermax 500-something or high 400 watt psu. Go with seagate or wd on the hard drive.
Don't listen to them on the 2 vs 1 dvd drive thing, it's only like 20 bucks more, and it makes it a lot easier. If you're that concerned with errors, well, then you can make a cd image from the lite-on, and then later burn it to a dvd/cd on the nec (which i have and like). I haven't tried the benq, but it is getting good reviews. Plextor has a sata dvd-burner at newegg which is kind of weird...
