He mentioned this on the show once. He didn't give the URL, but I think when he was talking to Elijah Wood about all of the strange web-sites dedicated to Gollum and Frodo, Conan mentioned that there is a site that is dedicated to user-submitted artwork of him fighting a bear . I meant to look it up, but I never got around…
I've done some checking around and it's an AMD SB750 chipset on the Mobo. The "controller" is a Firmware/driver-based RAID which like software RAID takes CPU cycles because it doesn't have it's own dedicated chip. No RAID for me unless I get a dedicated card. I might just use one as an external and use it for system backup.
