Yes. It’s on top of the board and caters for various lengths. I use the M2 as the boot drive running Windows 10, RoonServer and HQ Player. Music is stored on SATA SSD and HD.
I’ve set out the other components of the build in this other thread.. I probably spent too much on the PSU and could have gone for the lower model. I was able to fit a GamerStorm 120 Captain into the case with push pull fans around the radiator. Keeps the i7 nice and cool. I’d suggest a lower profile AIO though, particularly if you’ve got a normal size PSU.
It’s quiet, but not silent, so it sits in my daughter’s closet next to the listening room.
