HHDs (Hoarding Hard Drive)

Why on Earth did I store these 3 HDDs? I really can't tell...
They are over a decade old, and all of them combined might amount to something close to 14 GB of storage
I did use them on really old boxes around here, mostly, IIRC, on OpenBSD and as an Endian Firewall test boxen, but that might have been, easily, about a decade ago or so.
