Its still in my noisy IT room at work (multiple servers +AirCon) so can't comment on noise level yet. I'm on holiday tomorrow so will likely be taking it home to config/test so will report back.Is it as quiet as they say filled with drives or is it bull again like the G7
I have had the previous Microservers, still have a QNAP TS-469Pro and built a near silent i5 server so can give some feedback compared to those.
Just had Windows 8.1 on it and all went fine. The 16GB RAM just arrived so I'm now installing ESXi to a 2GB microSD card for a quick test.
I'd say windows-to-go will also install to the microsd card which is now a viable option with the new Sandisk high speed cards (16GB 90MB/s for under £30).
Single rear fan looks to be 120mm and easy to replace if needed. PSU fan doesn't seem to make much noise.
