I’ve gone with Unraid and consumer level hardware (intel i3 12100 and 16gb of standard ddr4 ram) the only “server hardware” I have, is an LSI HBA card that’s in IT mode so I can connect more HDDs.
I’m even used SMR drives in my array, just use a good CMR drive for parity and the biggest SSD you can get for your cache drive and you will be good to go.
Monsgeek M1 with Boba U4T switches, great for long typing sessions and for gaming. I have 45g springs as a lighter spring makes the bump more deifned.
