YMMV. ---- the mix of drives and cd's depends upon the usage. The issue being that a single controller apparently cannot access both the primary and the secondary devices simultaneously so if you wanted to access the hard drives at the same time (perhaps RAID 1), you would expect better performance by putting them on different controllers. If you plan on copying files to/from the CD/HD, then they would be better off on different controllers. The ATA 33 cables (40 pin IDE) and ATA 66 (80 pin) should be available at any computer store (I know that Fry's has them) and the analog audio cable should likewise be available at Fry's and perhaps others. If you can't locate an analog audio cable, I probably have an extra on laying around that you can have.
