Not sure I would have went with the CM fans, I've always had issues with their fans except for the SP120's, which are only for specific situations since they are about at loud as a box fan on high, but flow a LOT of air. Those Jetflo's are kinda loud too and require adapters to adjust to specific RPM. They are PWM though so hopefully your system can keep them toned down when they're not being pushed.
And as far as the disk drives go, I don't care what anybody around here says, or does, I'd want one on all my systems, except like my Windows tablet, as I occasionally like to pop a Redbox rental in to watch while I'm waiting somewhere and can't gain a connection there. Even for my desktop, there are good reasons for having on, aside from ripping disks and aside from any Windows related installations or applications. At least an external USB Blu-Ray, for sharing with devices.
