Unless you have 2 hard drives, you could do it with no card.
I'd start with the HD as primary master, and probaly both writers on the secondary and the DVD-ROM as primary slave.
If you use a card, you may have to use it for the HD, as some cards are not good with writers.
If you fancy a HD upgrade, it may be worth getting a SATA card and SATA hard disk, or a RAID card (I've seen ATA RAID's unbelievably cheap) and using a pair of hard drives in RAID.
