To be honest, nothing.
Running my home server on a nuc with proxmox and a 8 bay synology Nas (though I'm glad that I went with 8 bay back then!).
As a router I have opnsense running on a low powered mini pc.
All in all I couldn't wish for more (low power, high performance, easy to maintain) for my use case, but I'll soon need some storage and ram upgrade on the proxmox server.
Idk but in my opinion describing red*it as a juggernaut for hosting multimedia is a bit far fetched, since their own image / video hosting platform is pretty shit and most of the media content is actually hosted on other platforms.
