Hey there! 
I just got a Dell OptiPlex 7060 Micro with 32GB of RAM and had a Samsung 980 Pro Nvme SSD lying around, where I installed Proxmox on with ZFS RAID0. To better use ZFS I would like to get another one or two (enterprise) SSD's (the Dell has space for an additional 2,5 SATA SSD but I think with an A+E Adapter I can connect another SATA or M.2 to the Wifi Card slot).
I know that just plain Debian with these services as Docker Containers would totally suffice for my usecase, but I would like to use it as a learning experience aswell, hence ZFS and Proxmox
EDIT: I also have an external USB HDD connected which I plan to use for backups with PBS, so these are covered!

- Would it be advisable to get 1 SATA and 1 M.2 or 2 SATA?
- What would the optimal setup look like regarding on which SSD to install the OS on, the VM's, the data...
- RAIDZ1 vs. Mirroring two SSD's and keep the last single vs. ....
