Why not just use straight SCSI? It's better than IDE (and SATA).
Modern SCSI
is SATA with some additional features that the average person isn't ever going to use.
SCSI drives are expensive and low capacity... just like SSDs, except SSDs won't kill your ears in the process. If reliability is a pressing concern, set up RAID of SATA driver. Still cheaper and probably faster if you set it up right.
@OP: I'm pretty sure I took one of those servers out of a skip, gutted it, and tossed it back a few months ago...
