Hey everyone. So i figured i would try this again after thinking about what i might feasibly use in the next few years. I think my previous considerations were probably a bit too forward thinking. Just meaning that by the time i'm at the point where i'm needing to implement some extra storage, i'll probably be looking at a new build anyways.
I'm currently running a windows server 2008 machine that i am just going to try and get rid of for parts, since it really has no business in a freeNAS build. Plus it's a norco chassis that just isn't going to last much longer and i would like to physically downsize.
So my current line in the sand requirements are at least 10 drives. Mini ITX form factor, and as small and quiet as possible. It will be primarily a plex server with probably 1 - 3 simultaneous HD streams (perhaps eventually 4K, although i know that isn't feasible for any reasonable mini ITX budget at this time, so its not an important consideration at this time)

Case - Lian Li PC-Q26
Motherboard - ASRock Rack E3C236D2I
Memory - 32GB ECC RAM
Processor - Intel Xeon E3-1230 v5 3.4GHz
Hard Drives - Western Digital Red 8TB x 10 with a 500GB hybrid drive for the OS (pretty much the only part reused from the old server)
HBA Card - LSI 9207-8i (not sure if its worth it to look at the 9300 12GB/sec cards. I don't know much about these to be honest, but i thought i'd be limited by the sata interface not really able to max this out...? maybe i'm way off base?)
Power Supply - Seasonic G-750
OS - FreeNAS Coral running RAID Z2

Originally, i had wanted external ports as well on the HBA card for an external enclosure when my internal fills up. I'm at almost 32TB of data now and i don't see that getting any less. Looking at the rate at which i actually fill up the drives however, i'll probably be looking at a new system once that happens anyways. So i gave up on the external ports. I was having trouble finding anything that had enough internal and external ports anyways.

So all in all, i think this build isn't anything extra-ordinary. However, if anyone has any suggestions that might improve it i would love to hear it. The only thing i'm quite concerned about is the amount of available RAM on the mini ITX motherboards. I know that 32GB might not really be ideal for the amount of space i'll have. I read that it was recommended to have 1GB per 1TB of space, so i don't know if that throws up any red flags.

Overall to me seems like a great build except the 32Gb max ram support by the mainboard. With that much storage surely you would require? at least 64Gb ram? As far as hba cards go I'm not in the know on them except that the ibm m1015 in IT mode is the recommended card around here.

Yeah, the RAM was a concern for me as well. I am starting to think the build i want to do in the form factor i want just isn't possible if the 1GB per 1TB rule is a hard rule and not just a "you really should but it won't effect performance" type of rule. I must admit a certain amount of ignorance to the underlying tech of ZFS as I haven't really had much time to delve into the workings.
Thanks for the suggestion on the HBA card, i'll take a look at it. Looks like it has the same amount of ports as the one i was looking at, and the price seems relatively similar from what i've been able to find in a basic search.

I'm not quite sure why i never looked at them before but has anyone tried any kind of plex encoding for the Intel Xeon D SoC processors like the 1541? People have mainly used them for virtualization, and can't say enough good things about it. its passmark score is pretty insane. its a bit pricey, but it would allow me to go with 64GB of RAM... The Supermicro X10SDV-8C+-LN2F looks intriguing...

Once you get into the 32gb of ram range the 1gb for every tb doesn't matter much. At that point you are just scaling your system for performance.

Oh. well thats some good information. If thats the case it does open up plenty more options. Thanks for that!
