My Intel NUC server just died (whenever it's plugged in, it makes a buzzing noise, and the external power LED is off (the internal one is on tho)), so I need a new server box. Any recommendations?

I can salvage the RAM (16 GB DDR4) and hard drive (1TB HDD) off of this one, I believe.

Did you try another power supply?

I... don't know why I didn't think of that. I'll have to check if I have another.

Might as well repaste it as well

This is the most likely failed part, yes. If you feel adventurous, you can try repairing it like DiodeGoneWild. Looks like the auxiliary power supply (5V 1A independent of others; powers BIOS chips in standby to allow soft power-on) works but the main one does not. Unplug the connectors, connect the black (GND) and green (ENABLE) wires to signal a POWER ON state and check all the voltage rails. Many units use a powerful 12V supply and step-down converters to create the 5V and 3.3V rails, as well as an inverter for the -12V one – if that's the case, you can try backfeeding 12 V from another PSU and see if the rest come on. Once you identify the failed power supply, check its primary transistor(s) (big 3-pin components on a heatsink) for a short or open circuit.

This was the problem with my Synology recently. System would light up and "click" off over and over again. Replaced the PSU was all it needed.
