Question about Ugreen NASync DXP2800

We don't have much data, but I have a few Docker containers running at home. (HomeAssistant, Graylog, docmost, ddclient, pihole, portainer, wireguard - all in all 7 stacks with 13 containers) Does anyone have experience of how well Docker behaves on the Ugreen? (I currently have a small HP PC with 20GB RAM, 2.5'' SSD and an i5 at the start...) Is it possible to expand the Ugreen so that there is enough RAM available or would the system be overloaded with too many containers?
