3D print clamps for a tower of disks, use USB to SATA and build a Frankenstein NAS.

Better option Wyse 5070 Extended (100€) with LSI 8e (50€) used SAS controller to connect maximum of 8 disks and 3d printed tower. Something like https://www.thingiverse.com/thing:2939751

Change your approach.

My Homelab are 4 Wyse 5070 J5005 from eBay (100€ each), each pimped to 32 GB RAM and 512GB SSD. Each gives 4 cores and 10 GHz.

Totals to 40 GHz CPU and 128 GByte RAM. With some external disks and OPNSense Firewall the entire setup pulls 40 W in use providing 16 containers in total for 12 users. Each Wyse pulls 5.5W on average and is at 0.35 15Min load.

I run Seafile CE, IOBroker, Jump, Audiobookshelf, Taiga, Vaultwarden, Gitea, Immich, Paperless-ngx, Vikunja, Tandoor and others
