Old SCSI Drives

[tcg23]

I have two (2) old Seagate ST32155N "Hawk" 2.1gig Hard Drives, that have 512k of cache and run at 5400rpm.

I also have three (3) IBM DORS-32160 SCSI 2.1gig Hard Drives, IBM's support site is down, so I don't have any more info at the moment.

Does anyone think these are worth hooking up in an external case to use? It would be a little over 10gig of space between five (5) drives. I would love to hook them all up, but the only SCSI card I have is for a scanner with external hookup only.
Does anyone have experience with hooking up SCSI HDD's in an external cage?
I'd love any information possible on these drives, I am going to try IBM's support site tomorrow and see what I can find out.
All of these drives came from Compaq Persario Desktop PC's that were being thrown out because a big corp. was upgrading. The IT dept from where I got these pc's went through and pulled out the SCSI controllers and have us (me and my dad) the drives.

The data for the drive is here:

These drives are too slow and small to be justified for use in external cases. You'd get the equivalent of a 10GB PIO mode only IDE drive that consumes 5 times the power. You can get 7200 RPM 9GB drives for a song and 10K SCSI U2W drives are a little bit more expensive. Generally, if it's less than U2W, it's not worth the effort to hook it up.

I had them lying around, I was just wondering if they would be worth using. I already have a 40gig 7200rpm maxtor which is enough room for what I need.
