If the motherboard ports are SATA-only, you won't be able to run SAS disks from them.

Your best bet is a dedicated HBA.  If you're looking for basic hardware RAID OR the ability to present raw disks to the OS for software RAID, try an LSI controller like the 9211-4i or 9211-8i. That's 4 or 8 internal ports, depending on what you need. You'd probably want to look at: http://store.lsi.com/store.cfm/Host_Bus_Adapters/9211_Adapters/LSI00191

Replacing a PERC S300
I enjoy how Pandora can recommend new titles based off songs I already like. Is there a similar app that can take a few movies/shows I like and give me suggestions for similar ones?

EDIT: Showing the vids would be nice but what I'm really looking for is suggestions for other good flicks to watch, just the similar-theme aspect.
