Sanity Check for new Proxmox/Plex Build

I’ve been using Proxmox and Plex for a few years now on a single chip Intel XEON @ 2GHZ. The motherboard is an EVGA mATX board and every once and awhile the whole think locks up. I’m looking for a new setup and was thinking about the following:

Motherboard: Supermicro X9DRI-F
Processors: 2x E5-2650L v1
RAM: 128GB (8x16GB) PC3-12800R 1600MHz DDR3 ECC Registered Memory For Supermicro X9DRi-F
GPU: NVIDIA 1060 6GB (used for hw transcoding and I already own this)
CPU Fans: 2x Arctic 33

I run plex on the host os and have 5 - 4TB drives in software raid 6 this storage is shared with all the different VM’s that I run. I’d like to go to 5 - 6TB drives using ZFS.

The only thing left is to find a case. I really wanted rack mount but the Rosewill is getting hard to find. I could base this whole thing off a Supermicro case but those PSU’s are loud and do not have the power for the GPU that I’d need.

Any thoughts/opinions/suggestions?
