Technically, yes.  Likely unsupported though.  And you might have to
remove the CD-ROM to make it fit.

However, it only has two channels, so what your propose would require
putting two drives on one channel.

However, what you could do is buy a bootable SCSI card, and put the OS
drive and CD-ROM (presumably an external unit) on SCSI, and but the two
data drives on the two IDE channels.

Small SCSI harddrives are cheap (I'm thinking a 4 or 9 gig is more than
enough here), and the SCSI cards are also cheap (I think mine was a $12
BIN from ebay).
