So I got these nice 18GB 7200 RPM UW SCSI drives, and found they ran too hot for my existing computer case. What a bummer! Guess I'll have to look around for external SCSI boxes. But boy, were THOSE hard to find! So I sat down and took a few days to hunt down all the manufacturers and distributors I could...and here's the fruits of my labor. Hope you find it useful.
