Jonsbo N1 build check please (TrueNas/Jellyfin)

Could someone kind please sanity check my proposed build - intended use is TrueNAS/Jellyfin

I'm assuming that the CPU integrated graphics (Intel UHD Graphics 770) will be able to transcode H265 for Jellyfin.

I'll be using a Gigabyte Intel H610I DDR4 PCIe 4.0 mini-ITX motherboard not stocked by OcUK so that will sadly be sourced from elsewhere.

I've got 8GB of DDR4 Ram to use and an old M.2 256GB SSD plus 3 3TB HDDs that I will start off with and maybe upgrade over time.

My basket at OcUK:

1 x Jonsbo N1 Mini-ITX Office PC / NAS Server Case - Grey (SKU: CA-029-JB) = £124.99
1 x CORSAIR SF Series SF750 Fully Modular 80 PLUS Platinum SFX Power Supply (SKU: POW-CRS-02468) = £144.95
1 x Intel Core i5-12400 2.50GHz (Alder Lake) Socket LGA1700 Processor - Retail (SKU: CP-6AL-IN) = £169.99
1 x Noctua NH-L9i-17xx Low Profile CPU Cooler - 92mm (SKU: HS-03Z-NC) = £39.95

Ram, SSD and HDDs will come from parts I already have.

Total: £491.87 (includes delivery: £11.98)

That will do the trick, the CPU is more than you need but no harm in that. When I built my server for similar uses (Unraid/Plex) I went down the N100 route for power saving/cost. I also was originally going to get the N1, but swicthed to the N2 as the layout seemed better for airflow.

The only niggles I had with the build were replacing the case fan for a Noctua one and just the routing of molex and SATA cables - I think I had to trim some plastic off a molex to get it to fit. But like I said, that was the N2 case.

The PSU is probably vastly overkill unless you’re planning to seriously expand the NAS, something 450W would be more than enough

The i5 12400 only has the Intel UHD Graphics 730 gpu.... think it's 12500 or above with the 770 on 12th gen.

I have a 13500 in my unraid server for which does have the UHD770 and seems to work fine in Jellyfin for transcoding. Not sure how much difference there is between 730 and 770 when transcoding

Wouldn't spend that much on a NAS CPU. No way. Also PSU is ott.

the CPU in my NAS is realtek quad core, and plenty fast enough for everything, I don't transcode. I'd just go for a cheapest CPU tbh with onboard GPU, AMD or Intel, lowest power, lowest heat

TrueNas (ZFS) is heavy on memory and very light on CPUs. I’d focus spending on storage, memory and a board with 4 memory slots and at least 6 SATA ports. The CPU, power supply and PCIE speed is pretty irrelevant unless you need 50 gigabit+ networking.

Good points. It's for home use only so form factor is important hence the mini itx board.

Cost is also important. I already have 8gb of ddr4 so would like to use that.

Are there any ddr4 mini itx board with 6 sata slots natively?

I'm down this same rabbit hole ATM. Still scurrying around but i'd sort of settled on a 12100/13100/14100 CPU. Why would I go higher spec for a home lab type and build?

I struggled to find a MOBO in mATX from with 6 or more SATA ports.
