Additionally, my home Pi4 sits in a metal case that acts as a heat sink so I don't have to use a fan at all. That translates to: - additional energy savings - more or less eliminated need to clean out dust or eventually replace a fan - no fan noise, a massive boon if you live in a small apartment and don't have a closet or basement you can toss the server into for noise insulation I suppose if I did serious number crunching on my home server, I'd need something beefier... but I've been running a VPN, a Minecraft server, a streaming media server, and a DNS server on my Pi4 for more than 3 years now. Only during media scans do I feel any slowness.
