I'll probably take mine apart at some point to see if there's a CEC header as the BIOS seems to suggest. If it's there and the header seems to match what the Intel NUC's use, I'll get the Pulse8 adapter for it and test. Ofcourse, I'll also share pictures for the community to see
I probably am not the only one that wants this.
If it doesn´'t have the CEC header, I'll try to see if I can get a response from the Pulse8 team, asking if the CEC Adapter is compatible with HDMI 2.0b (or newer) and thus would not disrupt any 4K60 UHD (or better) content. Otherwise, I'll get a wireless keyboard that uses a dedicated RF transmitter which does not rely on the OS. Those should be able to wake up the system.
As a side note, my system doesn't have bad coil whine. It does make a tiny bit of electrical noise, but it's so low volume that I have to put my ear right up to the box in a quiet room to be able to hear it.
