Too bad you're not interested in putting drives inside of the case. 3Ware makes great cards, they're inexpensive, and do hardware raid 0, 1, 0+1, 5, and jbod. You can typically pick up the a 6410 (32bit, 4 channel card) for $99 + shipping, or a 7450 (64bit 4 channel) for $340. They work great in linux, Win98, and win2K. They also make an 8 channel card that's 64bit, but its a lot more expensive. If you're mainly concerned about redundancy rather than speed, the 6000 series are perfect for the budget and work nicely. And, they are faster than those Promise and High-Point controllers that are on the mainboard - those are basically WinRAIDs (like WinModems) - the driver is what controls the drive access, not the card. Cheers.
