What do you need it for? Using just HDD this server will be kinda slow. If this is just about storage, I'd recommend getting a good VPS from Hetzner, Netcup or php-friends and extend storage using a Hetzner Storage Box. 1TB for just 3,xx EUR or 5TB for around 12 EUR.

As a benefit you'll not have to deal with failing drives and you do easy backups using snapshots.
