Will this be overkill or otherwise not recommended for someone who is new and just starting to learn?
My goal is to have something I can grow into, but initially I'd like to host a few VMs, game servers, and a have place to store content. I'd also like to host a PLEX server in the future as well but might buy a separate piece of hardware for it specifically down the road. Thanks in advance for taking the time to help a newbie!
The mini PC crowd will inevitably come in and shit on anything bigger than a matchbox that uses more than 1w.
They're not 100% wrong: power consumption is a factor but there's also a time and a place for rack servers. That time and place is when you have (or are looking to get) a rack and are looking for rock solid reliable hardware with lots of cores and hotswap storage bays, and running game servers is definitely somewhere the low core counts of mini PCs falls down.
That said, in 2023 it's probably not worth spending money on anything older than an E5 v4.
Absolutely this. The power and heat from older servers is a significant factor. I'm running a r720XD and it pulls about 300w under normal load with a typical home server setup of VMs with home assistant, Plex, truenas, etc.
I would love to upgrade to something like a v4 cpu, but I'm leaning towards micro PCs in a cluster because of the size and power constraints.
