Personally, I'd do it like this: 16 x IBM DTLA-307075 @ $550ea (approx) 2 x 3ware Escalade 6800 @ $500ea (approx) You can get 24" ATA-66 cables from 3ware (or get them custom cut), which will greatly simplify cable routing. Presto; a terabyte for under $10k. Since you need to use something to stripe the two arrays together anyway, it's really a matter of preference between the 3ware controllers at 8 drives each or your average addin ATA card at 4 drives a pop. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also. But not because people want to be opponents, rather because the tasks and relationships force people to take different points of view.
