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.

    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.
