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.
I have some of these.
One is configured with 2x Xeon 10 cores, 192 GB ram and 5x sas SSD. Idrac is telling me that it consumes around 120W which is not that bad if correct. About the noise: obviously it's louder than a desktop but it's not that bad. I had it in my office for a few days while I was setting it up and it's like a loud gaming desktop. It's way quieter than my old Hp server or the R710.
