Depends on your personal use case of course but for comparison I have a (relatively) piddly Intel N305 processor mini PC with 16GB of memory and currently run a 25-30 container load, including Plex and a torrent server. My setup currently idles at around 20% CPU and 25% memory utilisation, so I can quite confidently say the linked N5 ought to give more than enough headroom handle a typical homelab/self hosted load.
