You may want to check out the PCI-X version of this controller that
LSILogic just released (MegaRAID SCSI 320-2X).  PCI-X is backwards
compatible with PCI, but also gives you greater bandwidth if your
motherboard supports it (at least, that's the marketing fluff).

Adaptec and Intel makes (PCI) controllers with similar specs to the one
you mentioned.

The Fujitsu 15k drives look sweet :-)

You may want to check recent archives for RAID threads.
