No I don't. The FriendlyElec NanoPI R6C can be brought to 1W Idle including NVMe SSD and 2.5GBe (and REAL transfer rates of >200MB/s). It's more expensive, but totally worth it in my opinion. See https://www.hardwareluxx.de/community/threads/ultra-low-powe...

Since it has neither ECC nor support for common Open Source NAS Operating Systems, I still would not buy it as my daily driver. I just don't think that a difference of 5W Idle Power is worth the effort of milling out stuff, using USB-Storage and the additional maintenance effort keeping this system up to date.
