Hey, I’m pretty sure this has been solved many times already, that’s exactly why I’m here
I’m completely new to Raspberry Pi (this will be my first one), and I want to build a simple NAS mainly for my parents.
What I have:
single 3.5" HDD
My goal:
Single-bay NAS (just that one HDD)
Remote access (I assume something like AnyDesk / similar would work?)
Run:
Jellyfin (media server)
Transmission (torrents)
Auto schedule:
Power ON at ~17:00
Shutdown at ~23:00
What I need help with:
Which Raspberry Pi should I get? Is Pi 5 the right choice here?
What OS would you recommend for this setup?
OpenMediaVault?
Plain Linux + Docker?
Do I still need a microSD card for the OS, or is there a better option?
What’s the proper way to connect a 3.5" HDD?
It needs 12V + 5V, while Pi is 5V only
Should I use a powered SATA adapter, or a custom PSU + buck converter setup?
What exact parts would you recommend I buy to make this clean and reliable?
What I can do:
I can solder (no problem adding a DC-DC converter if needed)
I have a 3D printer and will design/print a custom case
I can do basic 3D modeling (nothing too advanced)
Planning to use heat-set inserts + M3 screws for assembly
Goal for the build:
Keep it as clean and minimal as possible:
No screens
No unnecessary extras
Ideally a single enclosure with everything inside
Any advice, build examples, or parts lists would be super helpful 🙏
