DIY TrueNAS build - Power consumption and performance for old socket 1151 systems?

[TheDarkCorner]

Hi!
I am currently on an extremely tight budget, and have found a bundle on Ebay Germany of a Supermicro X9SCM & 16GB DDR3 ECC RAM & Intel Xeon E3-1225 v2 plus heatsink for only 54€!
I do have an unused spare rackmount case, so this would be a super deal on the surface, especially for server grade hardware with IPMI.
It would need to power a bare metal TrueNAS SCALE setup with 1X LSI HBA in IT Mode & 4 3,5" HDDs.

Am i correct, that performance wise, this old CPU should be enough? I dont want to run Apps or VMs, at most Plex as a single App (likely not though).
i checked Intel's ARK for the CPU, and it supports AES-NI: Intel® Xeon® Prozessor E3-1225 v2
So i should be good on that front, right?

The other concern is power consumption.
What can i expect here?
The seller has also the option to downgrade the CPU to an i3 2100 or a Celeron G630T.
What kind of power draw can i expect from them, compared to the Xeon?

I know this are very specific questions, but maybe someone here can help.
My electrical bill is killing me, as i now have to pay 0.58€/kWh...

Thanks for any help!

Surprisingly, this is almost identical to my TrueNAS Core setup with the difference that i have an E3-1230 in it with 32GB ECC RAM and i run both Plex and Nextcloud on it. TDP for the E3-1225v2 is 77W where the i3 has 65W so don't expect a huge power saving from the downgrade. I also would definitely not recommend a downgrade from a Xeon E3 to an i3 as Plex does want some computing power and the Xeon is more than twice the speed of the i3.

Also TDP is about cooling, not power draw, and average power under normal workload is very different from max power.

If Plex is only direct-streaming, it's basically just serving files, so that 1155 system would be fine. If you plan on transcoding, I'd offload Plex to a cheap uSFF/TMM 7th gen or later (1151-1) with QSV. The media can stay on the 1155 NAS, exported over NFS.

Would you be so kind to specify what idle loads you get? If you know?

That is good to hear! Do you maybe have a clue about power draw in idle that i can expect?
