[SOLVED] Completely new to Proxmox: Getting setup

[MJFlanigan]

So I recently bought a dell power edge r720 server with 6, 4tb hard drives, 2 500 gb ssds, a hba raid card, 192 gb of ram and I added two pci e name 500gb nvme drives. I set up the 6 4tb drives in raid 10 and installed Proxmox on them and now want to set up the two ssd's as caching, but also set up the following on the server:

1. A nas and shares to backup the server and virtual machines as well as my computers on the home network
2. Homelab os: just need what os or container I should put it in
3. Install windows and ubuntu on those two nvme drives respectively.

Additionally I plan to buy an Nvidia card for gpu pass through eventually as well. Probably two of them.

Complete noob, got some stuff working but kind of lost on the rest.

Also would like to install Zabbix for monitoring.
