Yes those are cheap, and likely rebuilt or used drives.

First pick out your SCSI or RAID card, then be sure the drives you use 
match that card.  There are various cable and termination standards for 
SCSI, you need to be sure you are using all the same ones on the card and 
the drives.

If you are going to use these old drives I would opt to use NEW SATA 300 
drives instead.  These new drives will outperform those old SCSI models.
