the only 6bay lff cage for it i found online after a quick search was over $400usd.

as others mentioned, msa30 is scsi (yuk). along those lines, you’d want the msa60 which is sas/sata, plus somewhere on the server to connect it to. probably not cheap.

but i really don’t think it’s worth putting a whole lot of time or money into a 15 year box… at least not anything that can’t be used in or with newer stuff later.

i’d probably just grab some 2-5tb 2.5in hdd for media storage and use those before i bought something specific for that old hardware.
