External Expansion from IBM

Still stumbling. Looking for an external SCSI chassis for my whitebox. I know about the HP StoroageWorks, but looking for what IBM has to offer:

• Found this EXP400 on Ebay: Auction
• Lead me to an IBM web site for the EXP400 which is discontinued: EXP400 info at IBM
• Found the current Expansion Arrays, but they are all SATA or Fiber Channel: Current IBM Expansion Arrays

All in all, the EXP400 looks like a good product. Here are the drives that can go into it:

• 40K1023 73.4GB 10K rpm Ultra320 SCSI HDD
• 40K1024 146.8GB 10K rpm Ultra320 SCSI HDD
• 40K1025 300GB 10K rpm Ultra320 SCSI HDD
• 40K1026 36.4GB 15K rpm Ultra320 SCSI HDD
• 40K1027 73.4GB 15K rpm Ultra320 SCSI HDD
• 40K1028 146.8 15K rpm Ultra320 SCSI HDD
