Advice on Home Server Build

Hello

Here’s my plan build:

  • CPU: Intel i5-10600
  • MB: MSI model B460M-A PRO chipset intel B460
  • RAM: 2x Kingston HyperX Fury DDR4 2666Mhz
  • SSD: nvme Samsung 970 Evo - 500GB
  • PSU: Corsair 550W CV550 or Corsair CS550M 80 PLUS® Gold
  • Case: Nanoxia DEEP SILENCE 4 ANTHRACITE MiniTower

or this

  • MB/CPU: Asrock N100mAsrock N100M
  • RAM: 32GB
  • SSD: nvme Samsung 970 Evo - 500GB
  • ASM1166 x6 SATA
  • PSU: Corsair 550W CV550 or Corsair CS550M 80 PLUS® Gold
  • Case: Nanoxia DEEP SILENCE 4 ANTHRACITE MiniTower

I will use TrueNAS - My PC, Server and Router supports Gigabit speed.

I want to use RAIDZ1 and start with 3 HDD 16TB (Toshiba MG08ACA16T) one for parity and the other two for storing. I plan on the future to add more, i have read that this configuration is recommended up to 5 drives, after that RAIDZ2 is recommended, is that true?

On the server there will only be video files, i want to store my entire Bluray and 4K HDR collection Remuxed.

I will watch TVShows everyday so does that mean that the drives will be stressed constantly?

I will play locally on my Gaming PC but maybe in the future i will set up Plex Server (can i watch them but with no reenncoding through that), i have heard about transcoding but not really sure what that does for 4K HDR.

Also if i set my Plex Server later does that mean that i have to put the files again on the server?

On a final note you guys seem to really stress the power consumption, so how would i go to minimize it considering that i will watch content frommit everyday.

Is this good for what i wannt to achieve?
