I personally used an old NUC6i5 with 16GB Ram and 1TB SSD as my private "HomeServer" / "Media-PC" / "RemoteMachine" for a long time, mainly bought because it was (and still is) 5.9W idle power consumption while reasonable performance (way more than a raspberry PI at the time).
I also spent the money on an Akasa Passive case[1], which made the device very expensive in total, but it was worth it at the time. It's still running as a backup.
BUT: I really think the times of the NUC are over. Media-PCs are getting less important (Netflix, etc.). With dedicated boxes like Apple-TV and TV Recording they hardly play a role any more and for home servers there are better alternatives.
I recently invested some money into a used Fujitsu D3417 + Xeon homeserver and it runs Proxmox at 9.3W Idle. The performance is just on another level than any NUC with the same price tag and because it is upgradable and supports ECC RAM, the only drawback is it's size.
I'm still questioning the industry, why they don't provide affordable ITX or smaller sized boards with enough space for ECC (!) RAM and two or more NVMe-Slots as low power low cost Micro-Server appliance. Newer AMD Ryzen does inofficially support ECC but the Idle Power consumption is pretty high. This could be a niche, I would definitely get one of these, if it was good quality (like the DELL, HP or Fujitsu Servers). These boards exist, but they are nearly impossible to get anywhere. An example would be the Gigabyte C246N-WU2, which does run at an unbelievable Idle consumption of less than 8W [2]
