Hello all,

I recently bought an EliteDesk 800 G4 Mini i7-8700T (16GB), and wanted to ask for some advice based on the services I want to run on it.

Just had the following questions:

  1. Should I get a 90W or a 150W charger for it? (I don't plan on adding much more stuff to it down the line... but maybe there's something I'm not thinking of).
  2. Given the following services I want to setup, is there a certain way I should approach it? Or some of them that I should do first? Or any general tips?
Services:

- Syncthing (to have all my devices / laptops sync their Joplin / Obsidian databases to one place)

- Nextcloud (to replace google drive, etc, and have a private cloud)

-
PiHole

- Plex(?) - just light use or to experiment though I think. I don't watch much TV / movies. Optional.

- Private VPN

- Reverse Proxy

- Firewall? (not sure how necessary / complicated this is)

-
Hosting own website (might be more of a security risk / hassle than it's worth. Just a potential idea)

- Tandoor (recipe website)

- AI Services

- Running scripts at night, doing website scrape jobs at night, or any type of script jobs I might need done. Maybe pulling data from APIs, to feed into more powerful PC in my room during the day.

More Background:

  • I do plan on building a trueNAS from a old tower case I have, and that one would be the serious trueNAS / backup server / Plex server.
  • This mini PC I plan to use more as a service that will always be on 24/7 (mostly as a central hub for Syncthing and Nextcloud, and also to use as a reverse proxy and private VPN).
  • My main PC in my room is quite powerful, and I want to use that one for learning LLM's and any heavier jobs / computing.
  • I got my Sec+ cert not too long ago and looking to experiment and learn stuff to help land a job in the field (My background is Mechanical Engineering but I'm looking to switch).
Thank you in advance for any insights and tips!
 
Do not use ZFS as the file system for Proxmox VE.

ZFS is a filesystem that requires a large amount of memory.

Please use LVM instead.

Since each service is not a topic for discussion on the Proxmox forums, please calculate the required memory, CPU, and storage after actually running each service.

Short remark: running that amount of virtualized services on a host with only 16GB RAM will be no joy.
Thanks CWT - I'm looking right now for upgrading it straight to 64GB.

I wonder if I could do even more, on the EliteDesk 800 G4 Mini. I think I heard somewhere people have gone up to 128GB, I'm looking into that now
