EPYC3251D4I-2T vs X570D4I-2T + 3700X

Looking to upgrade my Freenas itx system (B450+3400G, 16GB nonECC, 2x6TB). Itx is a must, got no more space.
I'd like to have 64Gb ECC and use Proxmox as a hypervisor and Freenas and some VMs (pihole, etc).
I plan to have an Optane H10 for the boot drive and to host the VM's and passthrough 1 HDD (16TB) to Freenas.

As I saw, pricewise the embedded and the X570+3700X system would cost roughly the same.
Which one should I go with? Please share your thoughts, pros and cons. Thanks a lot.

The Epyc 3000 has the advantage that it'll use less power and enable you to use ECC RDIMMs whereas the X570 will be UDIMM-only. However, it's based on the older "Zen+" design rather than the Zen 2 you're using currently so the single-threaded performance and performance per watt won't be as good. Rather annoying there's no sign of Zen 2 Epyc 3000 chips yet, but take up of Snowy Owl seems to have been lukewarm at best.

I can't speak for PCIe passthrough and freenas support on AMD; that'd require more reading but a) my X470D4U currently has bugged PCIe passthrough support and b) I might be mistaken but a lot of people using FreeNAS were quite against using it with AMD systems (times have hopefully changed since then though). My system has been rock solid with debian (the basis of proxmox) though.

Would you be passing through an HBA to freenas or just a single HDD?

Lack of embedded Zen2 Epyc's leaks are annoying me too.

I'd like to passthough only the HDD like Patrick did it here, then later with another HDD. So without any HBA.

Fancy board sure, but with the x570 you all have these, + pcie4 and your upgrade path remains open in terms of cpu and cooler.

It was a hard decision, but finally ordered the X570. Would love to get a zen2 epyc, but zero news about that.

I made room for a 2nd system at the upper compartment of my inwin 909, with removal of 2 hdd brackets. just enough space for an itx + 2 x 3.5 drive

I have the 570 board with a 3900x. Let me know if you have any questions.

Got the board finally, but only with 4x16 kingston 2400 ecc. The rest almost remained the same, 3700x and a 480 gb kingston datacenter nvme and 2x16tb ironwolf pros. Building a box to replace my current truenas box (3400g, 16gb non ecc, and 2x6tb wd red).
Want to use proxmox with one ubuntu vm (pihol, max 2 cores, and 2gb ram) and truenas (i keep the 8 cores I think). How much ram should I give to truenas? The 2 ironwolfs will be used only for truenas. Truenas has 2 plugins only transmission and plex. I am thinkning to give 8 cores and 32-48gb (?) ram to truenas.
What do you think?
Thanks

I am building a server for ESX virtualization running TrueNAS on 1 VM and Windows and other OS's on separate VM's
This specific board seems attractive EPYC3251D4I-2T but the VMware EPCY support, the passthrough from the ESX to the TrueNAS VM etc. concerns me. I'm planning to use the Node 804 for this effect. Any comments in regards to this build?
