So I have some space on my server rack, but not a lot of money lying around.
What I’m trying to achieve is a nas setup for my security camera system. It has 30 cameras, and 4 drives fill up in 3 months. 3X3TB drives.
Looking on eBay for a second hand rack mounted NaS is pretty expensive. Could I build one? From a jbod or something? I’ve got a nice big space in my rack doing nothing.
(I know I could buy bigger drives, but I kinda like the idea of experimenting with something g different) ✌️💛
Sure you can.
I use Rosewill rackmounted cases because they're cheap and get the job done. They're a far cry from any enterprise gear, but that's not really needed in a homelab. Think of the typical material used on a desktop PC.
This is the case I use, but see if anything else jumps out at you:
Rosewill RSV-R4200U 4U Server Chassis Rackmount Case | 11 3.5" Bays, 3 2.5" Devices| ATX, CEB Compatible | 2 120mm Fan, 2 80mm Fans | USB 3.0, USB 2.0 | Black https://a.co/d/icPXCTH
The official Rosewill rails are pretty crap, so I used these. They work great:

Beyond that, where you want to go is sort of up to you. Really any motherboard / CPU / RAM will do if you're only using it for storage. I used a few different parts I had laying around already, and then got some open box ones off eBay for things I needed to finish out the build.
OS is up to you as well. I like unRAID because it's the "grow as you go" OS, but I've used TrueNAS in the past as well. Both are solid options but have a lot of different pros and cons.
Great tip on the rails!
