Yeah you’re definitely in overkill territory but it’s nice to have extra potential in your system for new services or if you want to play around with VMs, containers, etc. What I find is most common for home server setups is that their CPUs are overprovisioned and memory is under provisioned. In a home server context there’s a TON of CPU downtime but a lot of simultaneous services running consuming memory but not really doing much. But I see you’ve got plenty RAM to spare here so if you want to tone down the cost anywhere I’d say the best place is to tone down the CPU.

For the RAM, get 2x32 instead of 4x16.

Total overkill. I run the same services plus some more on $250 Dell R720. I spent additional $120 for 10 2TB 2.5" HDDs for storage and have 6 more bays for additional storage when I run out. I have less than $400 into my setup and still have room to expand.

I think it’s very overkill and you’re going to be sitting at like 10-15% cpu when it’s done. But for projects like this saving a few bucks is not worth it. You need room to grow.

fyi CPU is on sale now for ~$150
