Hello guys, iam currently planning my first unraid server setup.

The server will at first be used to save all the data from my family with the "parity" feature to guarantee the failure of a hard disk.

 

Furthermore it should be possible to host a few containers:
- home assistant

- vaultwarden

- paperless

- nextcloud

- and in the future perhabs a minecraft gameserver or a webpage

This are the best components i could find from a budget to 1500€ stand now:
Motherboard: AsRock W480 Creator [ECC, DDR4, 2.5Gbe, 8x Sata 3x M2, 3x PCI-E x 16 Slots, few usb ports]
CPU: Intel Core i3-10100 Comet Lake CPU - 4 Cores - 3.6 GHz - Intel LGA1200 [4 Cores / 8 Threads, 65 watt tdp, ECC unterstützung,boxed]
RAM: 2x SO - DIMM 16 GB DDR 4 - 2666  [DDR4, 2666 MHz, ECC]
Tower: SilverStone Case Storage CS380 V2  [ATX, 8x 2.5"/3.5" (Hot-Swap)]
Power Supply: be quiet! System Power 9 400W [ATX, 12V, Bronze 3]
SSD: Samsung 970 EVO Plus MZ-V7S1T0BW [M.2 2280, PCIe 3.0 x4 NVMe]
HDDS: 6x Western Digital WD Red Plus 6TB, 24/7, 512e / 3.5" / SATA 6Gb/s [CRM]

In Total: 1.342 €


Are there any suggestions for improvement? Is my build energy efficient? Is the power supply compatible with my components?
Thanks in advance for your time & answers

The power supply will limit quite how efficient this can go.

if you really want to sip power a different direction and no ECC is probably in order. If you haven't, read through the powertop thread.

I'm not sure how the CPU will do with all the sharing and future maybes - I have an i3 (granted, a nit older) in my backup server and it can't handle a "cached directories" plugin (also doesn't need it). I'm not experienced with this specific hardware or all the things you may run enough to be sure.

And finally - parity is not a guarantee, just a probability. Two parity drives improves the odds. Proper backup to multiple systems/locations is as close to guarantee as you can get.
