Well, if you NEED a DVD drive, then you need one. Only you can say whether you actually do. I personally have only used one once in the past 2 years (on a computer anyway), when my uni decided to give us stuff on disk, instead of on the website we use for everything else
so I had to put it on a USB key at the library...
If you still use quite a lot of spinning media then get the Fractal. Do you still buy music CDs and then rip them to your computer, or watch films on your computer. If you answer yes to either of these questions then you probably still want a DVD drive.
If it's something you do on rare occasions, then you could do what one of my mates does: He has his DVD drive taped to the inside case floor, because it doesn't look very nice and opens the side panel if he needs to use it (at most it's twice a year, so he considers it worth the hassle ).
