Thoughts? Well letting a chip reach 100c isn’t great, your OS stopped receiving any security updates in Jan this year, so you probably want to do something about that and the original FreeNAS suggestion (or its derivatives) was a decent shout and it’ll give you a better long term upgrade patch than the Synology. The kind of low end dual/quad core CPU’s we’re discussing here are for nothing at this stage, as is RAM, power wise don’t make the mistake of thinking TDP is a useful metric here, unless you run your CPU at 100% 24/7 it’s largely meaningless and the higher TDP chips such as an i5 will idle at nearly the same power as an i3 due to power gating. The only obvious question that needs to be asked is, what is it actually doing that will be edit from upgrading?
