New user looking for hardware and setup advice please

[Astaroth]

Hi,

I'm thinking about setting up my first Jellyfin server/homelab and would like some advice please. I'm already planning on getting a NAS for file storage and thought maybe that could host the content for Jellyfin too. For the server I wanted to get something small with low power requirements but also want to run Home Assistant on it. The hardware I was thinking of is:

Storage:
UGREEN or Synology 4 bay NAS
3 x 4TB WD Red HDD in RAID 5

Server:
GMKTec G3 Plus Mini PC
CPU: N150
RAM: 16GB (Can be upgraded to 32GB if needed)
Storage: 256GB SSD or 1TB SSD

Requirements:

• Small, low power device if possible
  
• Max 2 local streams at once (no plans to set up remote access)
  
• Playback devices include: LG TV, Samsung TV via Roku stick, PC (Chrome/Edge) and iPhone/iPad (App or Safari)
  
• Media quality would be mostly DVD but probably some Blu-Ray too
  
• Host Home Assistant with a few addons too
  

I would appreciate some help/advice with the following questions please:

• Will the hardware above be capable of what I want to do?
  
• What codec/quality etc. should I be using?
  
• What installation method would you recommend? E.g:
  • Proxmox with HAOS on a VM and Ubuntu LXCs for Docker and Jellyfin (saw this on YouTube)
    
  • Ubuntu with Docker containers for HA and Jellyfin
    
  • Something else?
    

I've seen mention of things like Portainer and CasaOS for easier management too, but I believe it's better to run HAOS instead of a container for addons and the supervisor. I'm not really sure what's best as I've never used any of this. I'm experienced with Windows Server and Hyper-V VMs as well as programming/scripting etc. so I'm not scared of anything technical, but I have very little experience with Linux or containers so I'll have a lot of learning to do lol.

Thanks
