Recommendation for a SATA DVD Burner, I got this
ASUS one, seems pretty quiet most of the time, I think mine was the retail bundle, comes with Nero 8 which is OK. The only thing is with some DVDs it seems to take a few seconds longer to read them for autoplay to pop up, but nothing too annoying.
Case depends on what sort of budget you're looking at. Antec 300
is really nice, If that had been around when I got my 900 I probably would have got it instead, it's got loads of features they learned from their mistakes on the 900 with dust filters, better cable management etc. If you want cheaper than buying new then check out ebay you can sometimes pick up a real bargain and it's much less risky buying a case than hardware.
