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?
