UmbrelOS Use Cases | Raspberry Pi 4 + 4GB RAM + 1 TB External SSD

Hello,

After making the transition from a Raspberry Pi 4 4GB RAM w/ 1 TB external SSD to a NUC for Bitcoin-related applications - working great thus far - I am now left with this aforementioned Raspberry Pi.

Therefore, I am thinking to repurpose this device for running the following apps on UmbrelOS:

Vikunja
LibreSpeed
Nostr Relay
Nextcloud
Ollama/Open WebUI

To what extent is this possible with this device? Which app(s) would likely ask too much of its specs and therefore is/are better not to install/use?

Thanks in advance for your advice!
