Currently running a mini-ITX build with an Asus H87I-PLUS, Intel Pentium G3220 and 4GB of RAM which i'm looking to upgrade. It runs mostly as a storage server with a few Dockers (Radar, Sonarr, etc.. + downloaders ). There's no VMs running on it, but the docker clients are starting to hit the limits of the CPU+RAM.
It's been a good 5 years since I last needed to buy any hardware so no longer up to date with what's what.
Searching around leads me towards looking at something like an ASRock B450 + Ryzen 5 2600, but I'm unsure if that's going to be overkill (no plans to ever run VMs for gaming on it) and whether a cheaper option would work fine for it.
