I'm looking to make the move to unraid but figured it might be wise to let others eyeball my plans first to make sure I'm not about to step in something with my build. My needs are pretty tame, I've got about 25TB of data spread across a couple of snapraid arrays. I'd only be using this unraid box for the media storage and to run plex. At absolute most I'll only ever be transcoding 3 streams at once, and realistically it will only be doing one at a time 90% of the time and two at a time occasionally.
With this in mind I'm going pretty budget for the board/cpu, this is primarily to get everything consolidated, move from multiple single parity snapraid arrays to a single double parity unraid setup, and to give me some room to grow storage wise.

HBA: H310 PERC flashed to IT mode
Power Supply: EVGA 650 B5
Drives: Seagate IronWolf 12TB NAS Hard Drive x 8 (2 for parity, 6 for data)
Cache Drive: Kingston NV1 1TB M.2 2280
Unraid OS Drive: Sandisk 32GB Cruzer Fit CZ33 USB 2.0
Misc:

As you'll see I'm being pretty cheap with everything I can. The only thing I'm already sitting on is the flashed HBA and a few of the IronWolf 12TB's. Everything but the drives is looking to only be about $700.
My main points of doubt are:
Should I shell out the little bit of extra cash to go with a i5-9400 considering my low # of transcode requirements and that I don't plan on running any VM's or dockers other than Plex.
Am I making a bad call going for a cheaper board and older CPU, or am I just building to my actual needs.
Of course if anybody see's anything wrong other than that, any input would be much appreciated!
