I have no Idea what you just said. What are the opticals? I'm confused
I can answer question number 2 though. It doesnt matter. You just go into bios and set boot to CD first. For the Hard drives you plug the moltex connectors on them. Same thing for the CD drives. And for fans, the dfi boars has places where you can put the fans, OR you can use the moltex connectors if your fan has an adaptor.
Finally, you should follow instructions on the little DFI thingy that comes with your board. As for the HS/Fan, just unclip the little clippy things, and it should come right off.
UPDATE: I DO NOT KNOW WHAT I AM TALKING ABOUT WHEN I"M TALKING ABOUT THE HS/FAN. I HAVE ONLY INSTALLED P4/p3 FANS BEFORE. MONARCH INSTALLED MY FAN FOR ME WITH MY CPU, SO I HAVE NEVER PLACED A HEATSINK/FAN ON AN AMD 64 SYSTEM BEFORE. I COULD BE TOTALLY OFF. USE MY INFORMATION AT YOUR OWN RISK.
