Comments
- 0dB works as advertised, this is also otherwise pretty cool and quiet enclosure.
- Coil whine: there's coil whine and it's pretty loud with otherwise silent setup. It seems that this is a common issue with XG Station Pro, most likely due to the external PSU. I used the same graphics card in mini-ITX setup before this and there was no coil whine. I'll see what can be done about this. Maybe slight undervolt or overvolt can help.
- Windows sleep doesn't work properly, I need to look into this. NUC goes to sleep and then wakes up almost immediately.

One option for fixing the sleep situation would be to use the iGPU for desktop and only power up the eGPU when gaming. That would of course mean running two cables to the display and some display management. But this would also somewhat mitigate the coil whine issue, since it's not so audible when gaming.

@cthulhu Have you tried loopback mode performance? I have a similar NUC build that have the HDMI cable always connected to my TV. Whenever I need to use the eGPU, I simply power it on and through Nvidia Optimus the GTX 1060 eGPU can accelerate the TV through iGPU-connected HDMI cable. I also have the NUC in sleep mode daily with eGPU connected and never experienced immediate wakeup issue.

That was a very good tip! I tested the loopback mode performance today and it's surprisingly good compared to attaching the display directly to the eGPU. This seems like agood solution.

@cthulhu Glad to hear the loopback performance is good.
