I would haunt eBay for an old file bay, such as an HP Proliant or a NetApp, then get an HBA card, and hope there is a spot in my house that isn't going to be bothered by the noise. There's a seller called theartofserver on eBay that repurposes old enterprise grade stuff for self hosting use, and I got a card that connected a NetApp file bay to my old 4th gen gaming rig, and that's where all my files live now.
I've lost a few drives over the years, but no files.
