Old Thin Clients - Which CPU is fine? (sopuli.xyz)

I am currently looking for Thin Clients on ebay to use as my main server instead of the RPi 4 with an external USB drive.

I found decent offers for:

  • Dell Optiplex 3020M with i5-4590T 4GB RAM 120GB SSD
  • Dell Wyse 5070 with Celeron J4105 or Pentium Silver J5005 both with 8GB RAM 64GB SSD

Given the current prices of new hardware my questions are:

  • Should I go for 8GB RAM?
  • Or are 4GB RAM fine and I should take double the storage?

Things I want to run on this server:

  • Karakeep
  • FreshRSS
  • Paperless-NGX or Papra
  • Immich
  • Booklore

Because I plan to mostly use podman I tried to check for virtualization and all three suppoert Intels VT-x technolgy, will that be fine for my use case?

Immich needs RAM so opt for more RAM if possible. I'm using Yunohost on an old box and have 8GB and Immich uses about 4-5 with all advanced features off.

I don’t know what up with your Immich instance but this seems like a lot of RAM usage for me. I have 45 docker containers, including Immich, running on a 10 yo NUC with 8 GB of RAM and that’s not an issue… I use 4,7 GB total in this instant.

Seems like a lot of ram for immich.

its probably hoarding it as "cache" when it thinks no other program needs it. maybe it would release some when the system has memory pressure, but this is terrible because those mechanisms are reacting very slowly

Thanks a lot for the heads up!

I’m running Immich on an old ThinkCentre with the default feature set. Currently looking at:

  • Server: 1.4 GB
  • ML: 288 MB
  • Valkey: 8 MB
  • Postgres: ~500 MB

There is a bit more overhead for the control plane and cloud-native PG operator/backup pods but my instance fits comfortably inside a ~4GB allocation.

Well ok let me clarify, Yunohost says during install it could use up to so with a lot of the stuff disabled I'm sure it's not a full 5gb.
