How much storage are you actually using? You could just split it between the r230s and set up zfs replication in proxmox.

It should have power monitoring in the idrac already.

A wiki would be great, since it allows user contributions and a familiar interface.

Not necessarily mediawiki, though. Or maybe something that allows people to submit individual options in a category and vote on them.

Get it running and set it loose!

I have the N3. Works great, no issues cooling.

It looks like the problem with the N4 would be the clearance between the CPU and the case. You’d have to have a very low profile flat cooler, or a blower fan (noisy).

I’d check the specs and verify the actual dimensions of what you can use, and whether that would be sufficient for your use case. Remember that you also need room between the fan and case for air to actually move through.

Actually I just looked again and the top of the case is perforated, so maybe that won’t be an issue? It will restrict airflow of course, but it shouldn’t be that much of a problem.
