Built in KVM is not that important any longer, with all the new options for adding an external one. gl-inet comet kvm, nanokvm pro, jetkvm, etc.

Came here to remark about ECC as well.

The remote KVM options from HP and Dell and whatnot are usually so useless they might as well not exist except from remote power up / down, so I don't really care about that.

for thousands of dollars, plus what if you don't want remote-in?

I just bought a consumer AMD B850 board that supports ECC when I built my NAS in early October. I also got 32GB of ECC memory for $180 which is a distant memory today lol.
