I just recently started my journey setting up Plex with *Arr and have had a blast. I have the setup running on a raspberry Pi. Before I start buying a bunch of external hard drives, I went searching for some dedicated server hardware to comparison shop. Am I crazy to consider buying an old tower server for this, or will a raspberry Pi work just fine for this purpose? I don’t have that much experience but I do enjoy a good challenge.
I run mine from an old intel NUC that i got for cheap, its significantly more powerful than a raspi for very little extra power. Mine draws less than 8W running 4 VMs (pi-hole, VPN, my home assistant, and one I’m soon setting up as mediaserver).
