I am use to Midtowers, but my new system is using the New Antec PLUS Grey Metallic Case 1080AMG and I am using MSI KT3 Ultra2 Board with Just one hard drive, floppy, DVD, and CDRW. I am pretty sure the 10inch Round cables will be fine for the Hard Drive mounted in the lowest spot, and the Floppy as well since the connectors on the MB are near the Hard drive. But what length cable will I need to get the DVD and CDRW into the top two slots? I see duel cables at SVC for 36inch, 24inch, and 18inch, which is best? Thanks
